Fitness Nerdery, Or, In Which "Jetson" Joins My Household

I'm choosy 'bout my roommates, but I find,

Approaching an "-ish" age as I now am,

That body needs as much work as does mind

If I, in fact, do really give a damn

About my having any chance to see

The "rapture of the nerds," as we have called

That point in time, the singularity.

Commuting on my bike's a start, but lawd,

It's been so dark and cold! So now I've bought

A treadmill - manual - for those bleak days

When Deep Blue's best left home. And now I've got

A hankering to find one or more ways

To make of it a generator! Yes!

Now if I can, that's anybody's guess!
