Annoyingly Incomplete Research Breeds Annoyingly Alarmist Message

I saw this article at ExpandedConciousness.com

“Why You Should Take Your Shoes Off Before Entering Your Home, Backed By Science”

It opens with:

While it may be commonplace in most Asian countries, the cultural norm of taking your shoes off before entering your home has yet to catch on in Europe and America. In Asian cultures it’s easily understandable as to why people remove their shoes before coming into a home as their meals are typically eaten on mats on the floor, and they sleep on rolled out futons at night.

A new study has researchers suggesting that maybe we might want to be more aware of what exactly we’re bringing into our homes via our shoes.

Bacteria in the home – Research conducted at the University of Houston found that 40% of shoes were carrying around the Clostridium difficile, or “C.diff”, bacterium. Infections caused by C.diff are highly resistant to antibiotics, which can lead to difficult and lengthy recovery times for anyone who becomes infected. C.diff is also able to survive in most areas of the household, including toilets, tops and surfaces, and wherever floor dust is found. Ready to take off your shoes yet?

Kinda scary, right? I’m always going to take my shoes off at home so me and my baby don’t get sick!
The trouble is, the article intentionally sensationalized and misrepresented the results of the research.

I read the research paper. The data and conclusions of the research did not match what the article implied. To paraphrase, the research said, “C.diff can get you sick. 1/3 of all our samples in homes had that bug on them. 40% of shoe bottoms had it, 30% of bathroom surfaces, 30% of floor dust. Wow, that’s a lot… we think… maybe.” And that’s where they left it.

So my takeaway is: don’t lick the bottoms of my shoes, the floor, or my toilet. Thanks for the tip, guys.

If they had compared rates of contamination in the different areas of the house, they might have come to some great conclusions. For example, maybe people that have shoe bugs are more likely to have bugs elsewhere in the house (IE, maybe people track the bugs in on their shoes) . Or maybe not. They’ve got the raw data, why didn’t they crunch the numbers?

They didn’t have a control group. They said that floor dust was contaminated, was tabletop dust contaminated too? Maybe if they had tested silverware, frozen pizzas, and kitchen tables they would have had the same 30% contamination rates. But we’ll never know because they did bad science. I know all about bad science, I did some just last month.

Frickin’ grad students and their research projects.

Frickin’ sensationalist websites and their fear mongering.

 

You can find the abstract (a short summary) of the research here. You can find the full paper via a library that has access to scholarly journals. I used my San Jose State University library access.

Chicco Keyfit 30 Car Seat Advertising is Intentionally Deceptive

Advertising for the Chicco Keyfit 30 Car Seat is intentionally deceptive.

chiccoshopThe Chicco website says that it holds a baby “from 4-30 lbs” but they never mention that there is a very important height restriction. This is a dangerous and deceptive lie by omission. (See the Chicco website) (local archive). But the manual is very clear that it supports a baby “4-30 lbs, 30 inches or less.”
30 inches

You might be thinking, “Yeah, whatever, that is a small matter.” No, it isn’t.

The average baby outgrows the car seat by weight when they turn 30 months (2 1/2 years) oldBut the average baby outgrows the car seat by height at 12 months old! (see the CDC height and weight tables) Our baby was 30″ tall at 9 1/2 months!

The manual dictates that the product lasts 60% less than its marketing claims. That is deceptive advertising. Imagine buying a car that had a 10 year, 40,000 mile warranty! Would you feel cheated?

The Amazon ad doesn’t mention this height restriction either (local archive).

We’ve had our Chicco Keyfit 30 Car Seat for a few months now and it has performed well. But our daughter outgrew it more than a year and a half sooner than we were led to believe by Chicco.

It is a fine product, they don’t need to stoop to this deception. This deception is dangerous for children because if you were to only read the marketing information, you might use this seat long after it was safe to do so.

I Was Sick, But Now I’m Well

I Was Sick, But Now I’m Well

In September and October, I had a string of medical issues. It magically resolved itself but it was pretty weird and scary.

Starting in early September, each morning and evening I had terrible joint pain and muscle weakness. For example, I was completely unable to hold my big 32 ounce mason jar glass of water with one hand like I normally do. A few times in the late evening when Megan asked me to take the baby I refused, doubting that I had the strength to hold her. Scary! I found myself walking a lot slower on my commute, swinging my legs like lamb-chops. Everything hurt!

Then in mid-September, my legs puffed up with edema and red spots. I gained 10 pounds in water weight. Below my calf, everything tingled all day and I had trouble feeling some of my toes. My ankles were so stiff each morning that I walked ridiculously. To not move my legs was uncomfortable so I had to walk around and wiggle my legs. I went to the doctor after this kept up for a few days and my balance was suffering. I remember the moment walking down stairs needing to hold the railing lest I fall.

My doctor ran two batteries of tests. She knew I had elevated liver enzymes and decreased hematocrit (how many red blood cells I had) and she ran more tests which only told her I didn’t have what she was hoping I didn’t have (hep c, an autoimmune disorder, some vitamin deficiencies…) The end result of all the tests and the doctor’s opinion was, “It’s probably viral. It should start getting better soon. Call me if it doesn’t.”

That’s it? Yipe. Well, happily, it was already starting to get better and over a few weeks I returned to full capacity. But it was full-on-scary to be told, “Dunno.”!

My theory: a rare tropical virus made the rounds in Kensington

July: my niece and her boyfriend went to Vietnam. When they came back, they both complained of backaches and headaches.

August: My wife started having bad headaches. We went to the hospital twice, once because the headache was just so bad, and a week later because it seemed like she was having a stroke (!!!). All the fancy tests showed nothing abnormal and she was ok in a few days and better in a few weeks. Doctors said, “It’s probably viral.”

September: my shenanigans. My doctor said, “It’s probably viral.”

Automotivetouchup.com Review

Automotivetouchup.com Review: Terrible.

My car got some scratches in September. I tried a scratch repair kit that I found online, Automotivetouchup.com. Their website looks professional but don’t be fooled.

The instructions for how to apply the paint were mediocre, especially considering they spent the effort to make a pile of good looking 30-second-long “look how easy it is!” videos enshrined on their website that skip steps to entice suckers. Go ahead and take a look at their instructions. (local copy)At a glance they look alright enough but read them closely. Could you actually follow them? Compare the instructions to their jazzy promo video on the subject.

The color match was poor. See these before and after photos (click to enlarge)

Their customer service was nonexistent. I sent them messages on their website on 10-13-15 and 10-24-15 asking for help and I got no response.

Today I googled “Automotivetouchup.com review”. Ugh. They get embarrassingly bad reviews from resellerratings.com. 33 reviews, 3.6 out of 10. Poor reviews for their product and customer service. I don’t have time to deal with this crap.

I know that scratch repair paints aren’t miracle cures. I was just astounded at how hard they are working at making a poor consumer experience.

I Loved being an Airbnb Host

I Loved being an Airbnb Host. For a short time, I let people stay at my awesome pad in The Mission on the corner of 24th and Valencia. I met a lot of nice people, had fun, and made some money. At the time, Megan and I were getting closer so I was staying at home more infrequently. I started when Megan and I were going away for “Island Time”. We had a friend tend to the place. It ended when, well, my landlord didn’t approve. But by that time I was spending much of my time in The East Bay with Megan anyway, so it was all good. Notably, the wild-west of short-term rentals in San Francisco has just ended with the passage of a few laws.

Bright Private Studio on Valencia

Description
The Space

This cozy, private apartment is located in the heart of San Francisco’s historic Mission District literally at the intersection of the hip Valencia street corridor and the culturally rich 24th street corridor. This is the real San Francisco and you’ve got the apartment all to yourself! 2 blocks to BART, walking distance to the best culture, food, drink, and nightlife in the city.

FOR SILICON VALLEY BUS RIDERS: We’re at the closest bus stop to SV that is in a happening part of town.

ABOUT THE NEIGHBORHOOD
Here’s a -partial- list of what you’ll find within 1 block of the apartment:
• Arizmendi Bakery – A true gem. This worker owned bakery opens at 7am with lines out the door. Eat their blueberry scones and die happy. Have their famous daily pizza and you will already be in heaven!
• Valencia Farmer’s Market – a fantastic small market with great organic and regular vegetables and all the staples
• Fiore Caffe – Italian espresso café by day in a super-hip environment, dinner plates like Pappardelle Al Salmone by night!
• La Traviatta (2 blocks away) is an island of calm and perfectly served Italian dishes on Mission Street. Famous for seating opera legends old and new
• Papalote Mexican Grill – I would tell you that it is the best local taqueria but rivalries run deep among the many local burrito houses
• Muddy’s Coffee House – A great local coffee dive: open early and open late!
• Gypsy Honeymoon – Find unique treasures and antiques
• Campfire Gallery – A super hip art gallery that just opened in 2013
• Yoga Tree – Bring your yoga mat to this serene temple of yoga. I recommend getting their intro pass for your stay: 3 classes for $20!

This is a busy neighborhood day and night, light sleepers might want to bring earplugs or take some from my stash.

The Valencia street corridor boasts some of the city’s best culinary delights. It honestly has too many places for me to list but some favorites include Boogaloo’s for breakfast, Range for lunch, and Garçon for dinner. It’s a very hip and comfortable place to stroll. And you -must- check out 826 Valencia, San Francisco’s best independently owned and operated pirate store!

The 24th Street corridor has terrific cultural diversity and food. Be sure to look for the famous Precita Eyes murals!

GETTING AROUND
The BART subway is just 2 blocks away and several bus lines are nearby.

At the gas station just across the street you can rent cars by the hour with the three major carsharing companies: Zipcar, City CarShare and Getaround. Consider signing up for one of these services before your visit. Try using Uber or Lyft as an alternative to a taxi.

Parking a car in the area is very tight during the week, parking is easier on the weekends. A paid lot is 4 blocks away.

HOUSE RULES

SOME TIDBITS

My apartment home is the perfect starting point for your San Francisco adventure!
