Since I’ve had an AARP card for almost ten years, the next decade moves me into another bracket for, let’s say, a sprint triathlon.  So with one rotation of the earth, I’ll be competing as the youngest in the bunch.  I’ll need the advantage since it’s my first.  While gardening certainly gives me ample exercise, there is nothing like the challenge (fear notwithstanding) of the unknown.  It’s more a commitment to health than competition.  It’s a commitment to trying new things, to pushing beyond comfort zones.  Where would we be if humans and others weren’t compelled to explore new territory?  As Anonymous once said…Do not regret growing older. It is a privilege denied to many.
