14. ROTF, LMAO

Laughing not only eases stress, promotes social bonding, and lowers blood pressure, it may also boost your immune system. So bring some humor into your life, whether it's through friends or even a new TV show (preferably mine).

15. Sweat till you're wet

If you can work up a sweat for just 1 hour a week, you'll enjoy a range of benefits: reduced risk of heart attack, better mood, and lower blood pressure. I like interval training on the elliptical, with 15 pullups and 15 dips every 10 minutes. Your muscles will become more efficient, so you'll have more stamina for more enjoyable activities that also work up a sweat.

16. Put it in the bank

Most people rank personal finance as their number one stressor, usually because they feel powerless. Stress not only shortens lives, it also drives people to habits like smoking, drinking, or bingeing on food. Keep some money in a special bank account, safe from your lust for a new television, and you'll establish an emotional comfort zone with major health benefits.

17. Have as much sex as possible

If a 50-something man could have sex 700 times a year, the exercise and stress reduction would make him look and feel years younger. I wouldn't recommend quitting your day job in order to hit that number--but what's the harm in trying? The next time your loved one says she has a headache, tell her she's literally killing you. It works for me.

18. Know your numbers, and then aim lower

Take the part of your brain dedicated to your steak house's phone number and reassign it to your heart's vital signs. These include blood pressure (which ideally should be below 115 over 75), LDL cholesterol (under 100), resting heart rate (under 70), and fasting blood sugar (under 100). If your numbers aren't ideal, change your diet until they improve.

19. Add some weights

Just 30 minutes twice a week spent lifting weights can build significant muscle mass. What's more, working all that muscle burns tons of calories, making it a great way to lose your gut, too. Don't have weights? Try lifting yourself: Pullups are the most valuable muscle-building exercises I do. Oprah's trainer, Bob Greene, pointed out to me that pullups work the back, pecs, arms, and belly all at once. And since you're lifting yourself, you'll think twice before eating that doughnut, because you'll just have to lift it later. A simple setup in a door frame is convenient and inexpensive.

20. Grab your nuts

Nuts are among the best sources of healthful fats and protein around. I keep a bag of walnuts in my fridge and use their massive dose of omega-3 fatty acids to boost my brainpower while I see patients. Half of a handful eaten about 30 minutes before a meal will temper your appetite and help you avoid the drive-thru.

21. No, seriously, grab your nuts

Testicular cancer is the most common cancer in men in the 15-to- 35 age group, but it's usually curable if it's caught early enough. I strongly urge you to grab your testicles. Check them for bumps at least once a month. Each testicle should feel smooth and slightly soft, and one should hang slightly lower than the other, like two avocados (which, in Aztec, actually means "testicles") growing on a tree.

22. Hit the dance floor

Crosswords and card games aren't the only way to keep your brain razor sharp. It turns out that any kind of dancing with complex moves is stimulating enough to give your neurons a workout. Even the simplest moves provide some physical exercise. So don't be such a wallflower on your next night out. As a bonus, dancing may help you with tip No. 17.

23. Do your penis a favor and step on a treadmill

Men who exercise enough to burn 200 calories a day significantly lower their chances of impotence. That's because impotence often has the same cause as heart attacks: blocked arteries. Your penis is like a dipstick for your arteries, so check it. If you're interested in keeping it up later in life, lace up the sneakers now.

24. Learn to cook

Think you know how much butter goes into those mashed potatoes at a restaurant? You're probably off by half. If you can cook, you not only save money but also gain control over what goes into your meals. Plus, for most women, a man who knows how to cook is as sexy as one who stars in movies. I have trouble boiling water. Thankfully, I'm already married.

25. Some pills should be popped

The indoor life gives modern man protection from the elements and the ability to watch Gossip Girl in private. Unfortunately, roughly half of us are deficient in vitamin D which the sun is a major source. This crucial vitamin may aid in fighting cancer, diabetes, and heart disease. I take 1,000 IU supplement each morning.
