Young at heart with an old body

It is good to be young at heart as long as you keep in mind what your body can do. You may think how much fun it can be but be realistic about whether you can really physically do it. Heck when you are older you can pull a back muscle by bending over to pick something up off the floor. Exercise is good for you but running a marathon may not be possible. Don't wait too long to do the things on your bucket list because some of them you can only do with a young body.
