Protective power of helmets is way overstated. Science is a very objective thing, and so far the studies I've looked at are either bad studies (which is something that can be measured objectively, so this assessment is a fact, not an opinion) or do not show any significant benefit of wearing a helmet. I realize it's a tricky subject to research, but if helmets were so great surely there'd be better evidence by now, especially since there seems to be a huge number of people who desperately want there to be good evidence in favour of helmets.

At any rate, when people endanger themselves it's their own business. I don't see why it should concern anyone if nobody else is affected by their choices to any significant degree. But if careless riding by helmetless folks upsets you, it should upset you just as much when performed by helmeted folks. If sh*t does happen, they are not that much less vulnerable, if at all.

[qoute]even though there are dangers on the road...riding like a manic, weaving into trafficwithout a helmet is foolish.[/quote] Yes, it's pretty foolish. But no more or less foolish than with a helmet on. That is my simple point.
