Cub Scouts, I hold in may hand a pocketknife. This is a valuable tool because it can be used for many useful things. It is a dependable tool as long as the the blade is kept sharp and free from rust, and the working parts are in good condition. But if it is neglected and becomes dull and rusty, it can be dangerous. The same principle applies to us. we have a body, which when kept in good condition will serve is well. But if we fail; to take care of ourselves we can become rusty and dull like a neglected pocketknife. Do your best to keep fit!
