Mainly because HE did it.
The interesting thing is that these shoes just turned 16 years old last month. They started out as my shot put and 35-pound weight shoes for indoor track and field in college (because I apparently needed something to occupy my late afternoons after football ended and before tennis started); once those four years were over, they've served faithfully as my lifting shoes ever since.
I was thinking that was pretty cool, that my shoes were old enough to drive -- until I realized the tank top I was wearing for the gym today could have cast its first primary vote last month.
Needless to say, my clothing replacement cycle runs on geologic time.
