Like a Bolt of Lightning

I had just completed some work on my house that required me to climb around on a ladder for several hours. And it fatigued me quite a bit; particularly my lower legs.

I remarked to a friend. "Ya know, my poor granddad was climbing around on those things until he was almost 70. I don't know how he did it." Of course he did it for a living and I just do it as needed. But still.

About an hour later it hit me.

I'm within two years of his age. Jeesh.
