Laugh. A lot! But not so much that people think you're insane just having a good time. Delicate balance that one. Avoid stress and speak the truth. Move your legs, exercise. Sweating is good. Understand you're going to get old but you do not have to live old. Adopt a dog, or a cat if that's your thing. Don't eat frozen pizzas or garbage. Don't complain...change. Have sex, lots of it (see: exercise). Multi vitamins and omega threes! Listen to music, all kinds. Don't be a hermit. Go camping, talk a ride, walk the dog...or your cat in the park but don't settle on being boxed in by four walls. Use your common sense daily. If you drink, don't drive and if you drive don't drink. If you drink too much, get help. Don't get shot!
