Only 45 here but am already carrying a lot of issues from years of rugby/league, jumping out of planes, walking for weeks on end with 30kg+ on my back, getting drunk and treating the world like a jumping castle, etc. I haven't been able to run since arround 2000, which is part of the reason I got into riding bikes. I hope I don't ever have to downgrade in terms of activity but I reckon the writing is on the wall for me.Well I’m 61 years old and hope to remain ebike free for as long as possible.
