Electric scooters vs. electric bikes

IMG_20180403_164432.jpgI happily own an electric bike, but it’s not optimal for every purpose. So I jumped at the opportunity to rent an electric scooter, which is now possible in D.C., to see whether it’s better. For my purposes, it’s not, but for yours? Read on.

I rented a scooter from Lime four times to take short trips around town. Such rentals have great appeal to people with limited walking range (e.g. me) – especially for climbing hills.  But my focus here is on whether owning an electric scooter would be preferable to owning an electric bike. Before getting to the direct comparison, I’ll briefly discuss the positive and negative aspects of using an electric scooter for everyday transportation. Continue reading


Vision Zero after zero progress?

Tracy Duvall

Washington, D.C., like other cities around the world, is trying to eliminate traffic deaths through a program called Vision Zero. Inspired by Sweden, this has been a model project in many ways, but the lack of positive results is testing its proponents.

Effecting change per se is my topic here, rather than the specific alterations that D.C. et al. have wrought as part of Vision Zero.

Stealthing: Surveys won’t reveal it, trash might

A recent article in a law journal has drawn considerable attention to ‘stealthing‘: when a man secretly removes his condom and continues having sex. Aside from being a heinous violation of trust and hygiene, stealthing reveals one of the many weaknesses in surveys of condom use in East Africa. In short, people could answer honestly that they used condoms.

One of the many problems with condom-use surveys – aside from the rampant lying – is that they don’t ask how condoms are used. Continue reading

Vitamin B6 for ME/CFS: Works for me

Recent research suggests that levels of vitamin B6 in the gut distinguish sufferers of ME/CFS (myalgic encephalomyelitis, aka chronic fatigue syndrome) from healthy people. “Good enough!” says I, “I’ll give it a shot.”

First, though, I looked for information on the most effective form and dosage. Here’s what I found: Continue reading

Their goal is inclusive, so why not the app?

Recently, while searching for a story to report about world-changing, I read a press release about MyGIHealth, which seemed quite promising. As I understood it, people with gastrointestinal problems could use a free app or website to record their symptoms, get meaningful medical feedback, and share a rich record with their physicians. This seemed like a great way to help.

And probably it is for thousands of people. But it works fully only as an iOS app, so large numbers of potential users, including me, are shut out. Surely this results from a mismatch of goals and activities. Continue reading

Xero Shoes’ Amuri Venture: Hands-on Review


(They’re not actually purplish.)

I bought the Amuri Venture sandals from Xero Shoes more than a year ago. My main use of them has been walking, and I’m fairly happy with them. (I’ve also bought and reviewed Xero’s original and Contact DIY sandals and their Ipari Hana shoes.)

The main reason to buy Xero footwear is if you want the closest experience to going barefoot while protecting the bottoms of your feet. I’m not an ideologue on going barefoot(-ish): I simply found that I can avoid or recover from plantar fasciitis and Achilles pain by doing so. Continue reading

Xero Shoes’ Ipari Hana: Hands-on Review

xero-ipari-hanasXero has made my favorite footwear for more than six years. (I’ve bought – and reviewed – Xero’s original do-it-yourself sandals and their DIY Contact sandals, and soon I’ll add the prefab Amuri Ventures.) Sadly, though, sometimes I need to wear actual shoes – due to social expectations or the weather. So I’ve worn through a succession of “barefoot”/zero-drop/minimalist shoes from Nike, Merrell, Vivobarefoot, and Skora. But I always lamented that none quite had the salutary feel of the Xeros – if only they made closed-toed shoes!

Now they do – the Ipari Hana. So I bought a pair, and I’ve worn them for almost three months. Continue reading
