A tough, tough issue.
Someone posted that there are no arguments against seat belts. I lost
a friend, burned alive in a car while hanging upside down from his
seat belt which he could not get undone. He might argue that point if
he could.
Another friend lost his brother in a single motorcycle accident. The
Bell full-face he was wearing broke his neck when he landed in the
ditch and he suffocated by the side of the road. His family doctor
made the mistake of telling this to my friend, who had given his
brother that helmet as a birthday gift. He might be inclined to argue
for choice also.
That said, I ALWYAS wear my helmet when riding, ALWAYS wear my
seatbelt when driving, and ALWAYS wear my pfd when paddling. I've seen
and heard about too many deaths that prove the rule rather than the
exception.
