Well I actually never did, but it's that same old saying about how tough it used to be, ..and how tough we used to be. Last week I was vacationing in N.Dakota with the family and took the boys golfing (they like it!). I mostly ride a cart these days due to back problems but I used to walk and carry ..sometimes 54 holes in one day ..and often in 90+ heat, ..and could never get enough. My boys (16, 18) were "beat" after RIDING 18 holes (88 degrees). Wimps!
Then I helped my brother-in-law (the local mechanic) recharge the AC on two John Deere tractors. It was haying season and nobody would dare go out without AC. One guy let his Dad cut hay all morning until we arrived and fixed his AC. And everybody was baffled how anyone ever farmed on open (no cab) tractors.
(Rode 35 today. Perfect day.)
