Is This The Best Allocation of Valuable Resources?

Sometimes when I wake up there is a white hair jutting from one of my sideburns, directly perpendicular to my head, and obviously my body labored extremely hard to grow this gravity defying strand of hair in the span of a night, but meanwhile, my knee hurts and my back is sore from swimming and I still have some poison ivy . . . so my question is this: doesn't my body have better projects on which to work, rather than to grow these hairs?
