As a side note, I've gotten my dad into dirtbiking for the first time at 65.
He has padded shorts, and padding pants, and a padded shirt. He then wears my track leathers, even though he's on dirt. He's fallen a few times and he agrees you feel like superman.
He's started joking that if he makes it to 75, he's going to start wearing the padded shorts and shirt as regular daily wear.
I have always thought once I get to a certain age I might just start wearing a helmet...everywhere when standing. It will look silly, but maybe it's not such a bad idea.
