What have you done for your hands lately? Well they held a sandwich, raised a beer, cleaned up when you eventually spilled that beer, lifted weights, and tied your shoes.

Fortunately, cleaning up your act is simple (and much appreciated by your partner). Follow these seven steps for putting your best hand forward — no manicure required.
