Share the best tip you learn in 2008.

Mine is from Charles Atlas book, shower like this: with cold water in the morning no need to use soap or shampoo, letting the cold water hit you between your legs since you have a lot of nerves there. At night just before sleep have a regular shower with warm water and soap and shampoo.This will help you sleep better at nights and relax in the mornings.
