58. Suffering some joint issues, golfers elbow (not from golf), knee issues, back issues. Taking thyroid medication. Eyesight no longer 20/20. Can't do a single pull-up anymore. None of that seems to affect my riding, yet. But I'm only doing about 50mi/wk, mostly commuting.
10yrs? 20yrs? Who knows? I hope I'm still riding, still relatively healthy, still interested.
