67 here, still working full-time. I've been averaging 6/7000kms a year since 2002 when I re-started cycling.
Until last season, which was a write-off due to sudden onset of serious medical issues last April, which were not fully resolved until last December. Hoping for a better year this year, and a return to my 'normal' cycling routine.
Medical specialists say there's no reason to stop, and every reason to continue. I construe that advice as a prescription for a new bike (medical necessity). So I ordered one.
