The spine is the lifeline. A lot of people should go to a chiropractor but they don't know it.

I never think of my age, never. I could be 20 or 100. I never think about it, I'm just me.

Sex is the greatest driving force on this planet. Christ, why are we living if we can't have a little fun? Sex is giving, and the more you give, the better lover you are.

When I first started out, I was considered a crackpot. The doctors used to say, "Don't go to that Jack LaLanne, you'll get hemorrhoids, you won't get an erection, you women will look like men, you athletes will get muscle-bound -- this is what I had to go through.

Whatever you can handle, it's up to you. Pick something where you are going to do it to failure--in other words, where you can hardly do it. That's the key. So many people will just take five pound weights and do something 10 times. What are they getting out of it? Nothing! Say you are going to build up your bank account. If you put in a penny a day, it's going take a long while. It's the same with exercise--the more you put into it the more you take out.

Twelve to seventeen minutes is plenty on the treadmill--if it's done fast. That's all you need for cardiovascular benefit. You don't need to spend that extra time unless you are over weight and you need to burn off extra calories. Do it vigorously, like somebody is chasing you. You've got to do it hard. Otherwise, if you just take it easy and do it longer, you are spending all that time when you don't need it. Use that extra time with your weights instead.

Muscle cells strengthen in response to intense exercise - whether you're 18 or 88. But the intensity is what's lacking in most people's workouts. And there are doctors who'll give you the advice, "Well, don't push it."
