I hope you're warming up thoroughly before attempting those stretches, mate. You're reading all sorts of stuff into my posts, most of which isn't actually there.

For the record, and as simply as possible:

1) I don't advocate for or against helmets. I just advocate for intelligent adults making their own decisions, and not having to put up with insults as a result.

2) A helmet is of some -- but limited -- use. It can certainly prevent bumps and bruises, and in a certain kind of fall it can prevent brain damage and/or death. The "right" kind of fall -- enough energy to cause damage/death without a helmet but not enough to overwhelm the helmet's protective ability -- is unfortunately rare. Anyone who thinks it's going to save him when struck by a large, high-speed motor vehicle is kidding himself, regardless of what kind of degree he has.
