I'm 21, and I have found out somethings are inevitable and somethings are preventable. Needing to pace yourself more and having things not heal as fast are part of growing older. Framing on cement floors for 9 hours a day without kneepads then not being able to bend your knees the next days is preventable. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif I am not that old, but you do eventually pay for everything you did when you were younger.
