Everybody wants to be a bodybuilder, but nobody wants to lift no heavy-ass weights.

I've had back problems basically my whole career.

Bodybuilding is about building your body. Whether you do it to maintain your fitness levels, climb Everest, run the marathon, or be a competitive bodybuilder is up to you.

What I've always tried to do is pick short term goals.

Modern medicine has presented us with a Faustian bargain: Our aging bodies can bankrupt our children and grandchildren. We have run into the 'law of diminishing returns' in health care, where we are often doing more and more, with higher and higher technology, at more and more cost, for less and less benefit.

As people flock to urban centers where ground space is limited, cities with green walls and roofs and skyscraper farms offer improved health and well-being, renewable resources, reliable food supply, and relief to the environment.

The technology is not an end in itself: it is a tool. It can make it easier for us to communicate or manage our finances. It can help us take care of our health or help policemen in their work. It can create jobs and boost growth. It can enhance transparency and accessibility to services.

When you're singing, you're using extra muscles, and it requires a lot of exercise and breathing. You can't do that if you're a sissy. If I have any fitness advice for people, I'd tell them to sing more. It's good therapy, too.
