At 60, I've lost a bit of distance but not much yet. But I've gradually become much better at ball striking and scoring. I tell my wife I've got 10 more years of getting better, then I suspect I'll run out of tee boxes and have similar comments to John/Accufit above.
I sure wish I knew then what I know now. Mainly, stop swinging at 100%. Doing so leads to better ball striking no matter your age and swing speed.
