i think Joe beats Jones in his prime as well. The man throws to many god damn punches and he throws them 10000000 miles a second.
Go without a coat when it's cold; find out what cold is. Go hungry; keep your existence lean. Wear away the fat, get down to the lean tissue and see what it's all about. The only time you define your character is when you go without. In times of hardship, you find out what you're made of and what you're capable of. If you're never tested, you'll never define you character.
