I'm constantly amazed at the "Danger! Danger!" warnings heaped on
ordinary bicycling. It seems that millions of people "know" that one
cannot be safe riding a bike unless they wear a very weird styrofoam
hat; or garish, hi-viz clothing; or run bright lights front and back,
even in full daylight; or ride only on flat, boring multi-use paths,
because riding anywhere near motor vehicles can't possibly be safe.

Yet research comparisons between various activities almost always show
ordinary cycling (i.e. not gonzo off-road downhilling) to be quite safe.
I came across another relevant research paper today: "Active Living and
Injury Risk" by Parkkari, in the International Journal of Sports Medicine.

They used extensive surveys to evaluate risk of injuries per 1000 hours

activities - with lower numbers being better:

Ordinary (e.g. commuting) bicycling: 0.42 injuries per 1000 hours.
Walking;   0.19 injuries per 1000 hours
Gardening: 1.01
Home Repair: 0.54
Basketball: 9.1
Soccer: 7.8
Tennis: 4.7
Badminton: 4.6
Running: 3.6
Competitive cycling: 2.0
Dancing: 0.7 injuries per 1000 hours.

So if you're afraid to ride a bike on a normal road, you should be more
afraid of gardening. (And this is not the only study that found
gardening to be riskier than cycling!) Also, think twice before going
dancing, let alone the scary sport of badminton!

BTW, the paper says "when commuting to shop, office or school it is
safer to walk rather than ride a bike." I think that's a mistake. Since
whatever shop you're heading for is a fixed distance away, what matters
is the risk per km or per mile, not per hour. Bicycling's per hour risk
was found to be 2.2 times that of walking; but I think almost all
bicyclists ride faster than 6.6 miles per hour - that is, faster than
2.2 times the normal walking pace of 3 mph. So per mile, cycling is
safer than walking, a fact that pops up consistently in relative risk
studies.

Zen is apparently the only one posting here who still races. He should
take comfort in the fact that they found racing to be safer than badminton!

Another bunch of pointy-headed researchers wasting time and money on
surveys that people in real life don't care about.

I have to wonder what kind of pathetic look-at-me simpletons would
even respond to surveys like that and how eager were they to be
included and have their little boo-boos acknowledged by the
pointy-heads.

At any rate, I'll evaluate risks for myself.
