Our youth.
Once we have our own offspring to look after we realize we’re not as young as we used to be. Oh sure, we can keep up with the young’ns easy enough. But as the years past, so does our youthfulness. Our muscles need more and more time to recover after playing. We feel like we need more sleep. Hangovers last just a bit longer, too. You know you’re getting older when your aches and pains can predict the weather. Try as we may to hold on to those glory days, they will pass us by. Eventually our glory days fade into golden years. Right now, I’m somewhere in between.
But it’s our youth that keep us young. Those heathens of ours will need to be entertained at some point. For me, that means 100+ pitches while they practice batting. It means playing catcher while they practice pitching. It means jumping on the trampoline so they can get launched. It means that when I go for a run they will want to ride their bikes and I may have to give them a push up a hill. It means lacing up my skates and hitting the ice with them. Now that I’m over 40, my body doesn’t recover like it used to. But if it weren’t for the youths in this household I wouldn’t be nearly as active as I am.
They keep me young, until I feel old.
