I know I take more recovery time now. Whether it is physical/aging (61yo) or mental (bc I am no longer on 24hr call/duties) is a toss up...some days my head tells me I'm still 35---those are the times I am extra careful. If I am training on a schedule (usually Mar-Jul), I make sure to schedule rest/recovery. That said, I try to do something physical everyday, but I don't ride back to back days (and certainly not high effort back to back days) very often.
