Who Am I?

I'd say late middle aged and ready to retire well almost soon enough I still have grade school friends who remind me of days spent on childish errands I'm not my current work and never saw myself a job personified I'll only have one love one great love forever anchoring me on earth You used to say baby too much and now rarely so that something's missing you're younger than you think and far more active than many born years later You can play most team sports but should probably keep to maybe just baseball you can be loud and so stubborn that reason fails sacrificed on pretense He spends too many days with the classics the books cars that don't enrich life He obsesses too much over work deadlines and details that mean nothing He needs reminding not to turn walks in the park into stressful hill climbs He has such abundance so much good around him he really should say thanks
