No, I am not quite that old yet as pictured, but there are days I feel like that. Someone at worked asked me what I miss the most, what I wish I had back, and without thinking I said "The speed of my youth". When it felt like I could run for ever, play any sport, try anything and do reasonably well, without hesitation. Play hard, recover, and do it again. Not worrying about pulled muscles, huffing and puffing, will I make it in to work, might get hurt, and so on.
My car trunk when I got older had equipment for all sports in it. Tennis, check. Golf, check. baseball, check. Basketball, check. Hockey, check. football, check. Squash, check. And so on. Never a worry, never a care.
Yes, I know, there are many out there doing it all at my age and beyond, but sometimes you have to pick and choose what is best for you.
And yet it seems not that long ago, a different time when I was young....
