Wifey & I have been wearing helmets ever since we started our kids on bikes. wanted to set the right example, you know? kids are in their 20s now. last July 4th Wifey & I think to take a leisurely ride on a quiet paved trail without helmets cuz it was such a hot day. 5 miles from the car, she crashes & breaks her wrist. cpl months later, after that heals, she needed carpal tunnel surgery. she never hit her head but we both felt pretty dumb after the crash, cuz it could have been much, much worse
