This is pretty much what I was going to say. The other 44% apparently either can't live within their means or can't do the math of simple compound interest.

I'm not even a particularly well-paid developer, and my wife and I are about 80% of the way there (in our retirement accounts) after not quite twenty years of saving.

Perhaps it is not just the scientists, but the university administrators and those (legislators, for state schools) who hold the purse strings, who believe that the only credible source of research funding must be the federal government. Then they look at the humanities faculty and ask, "Why aren't you paying for your own research with federal grants? It must not be of benefit to anyone."

DudeTheMath (522264) writes "Cornell University scientists studied how fruit flies respond to flight disturbances (instead of wind gusts, they used carefully controlled magnetic pulses) and found that the flies recover in as little as three wing beats (at 250 per second) by doing some kind of calculus in a little "integrated circuit" of neurons that control the wings directly. The pitch and yaw results are already published, and the roll study is forthcoming. (NYT, partial paywall, autoplay of fly that starts with a car ad.)"

This (no mod points today). I'm a dynamite C programmer, some small experience in JS & C#, and I know how to design an rdb schema and write a stored procedure, but I don't have "4 years experience with jdb and Netbeans". Whatevs: give me three weeks with actual stuff to do, and you probably couldn't tell the difference, but it's darned hard to get hired.

Note that the CEO is trying to get the most out of his (almost always "his") employer, too. Who's his employer? Why, the board, usually full of banking CEOs who love to negotiate their high salaries, bonuses, etc., from their boards. It's largely a big circle jerk.

Where does this happen? I had a weekly commute across southern Michigan on US 12. Every eight to ten miles, there was another town, and the road widened from two to four lanes, allowing easy passing of anyone I'd been "stuck" behind. I always calculated my time savings (miles to the next town, desired speed, current speed) from a pass before I even checked for oncoming traffic. It did wonders for my blood pressure. I saw way too many people trying over and over, and occasionally making a really risky choice, to pass someone who was doing 53 in a 55 when there were only a couple of miles to the next town. So I'm making this suggestion only that one think before acting. If you can pass safely, by all means, do so. I'm not going to hold you up.

Also, reflecting my status as a former math teacher, I adjusted the numbers to reflect freeway driving and to get a "nice" answer; I read once that the average freeway commute was about eight miles.

I wish I could cite the study where I learned the overtaking statistic (I probably found it on the WashCycle blog), but the results were certainly consistent with my own experience. I've been buzzed, and once been bumped by a panel truck that probably thought it had completed its pass (although I was barely bruised), but I've never been hit from behind. It's the left cross that gets me every time. I have stopped signaling right turns when there's oncoming traffic waiting to turn left into the same street, because it seems as soon as they see my signal, they think they can beat me (I'm assuming they see me at all, of course), and keeping both hands on the bars gives me more control whatever they do.

Thanks for the critical eye on this. And, as I said, overtaking is the kind of interaction I'm least worried about, so it has very little bearing on my decision to wear a helmet. The risk (chance of the helmet making a difference) may be very low, but the reward in those few cases so high, that it's worth the minimal cost. The only times I've regretted wearing a helmet were on sixty-mile-plus rides where I could hardly keep my head up by the end due to neck fatigue.

Slows them down? Really? They can dismount it for the crit, right?

We already do the bright colors (I got jerseys in fluorescent green, fluorescent orange, fluorescent yellow, snow-blind white, and BSOD blue), but it just never occurred to me to have a flag. How 'bout I spray-paint a raccoon tail traffic-cone orange? Awesome.

One study has shown that cars overtaking and passing leave more room for cyclists not wearing helmets. However, being struck from behind is about the least likely kind of car-bike interaction (cars turning across a cyclist's path vastly predominates those statistics).

My wife is (likely) alive today due to her helmet (that is, she is alive, but likely wouldn't be but for the helmet). She left a helmet-shaped hole in the windshield of a driver who t-boned her while illegally driving in the shoulder.

I may never need my helmet, but I always wear it (well, almost; when I borrow hotel bikes in Europe, I don't bother).
