A muscle is like a car. If you want it to run well early in the morning, you have to warm it up.

Exercise is the chief source of improvement in our faculties.

Personally, I need a high level of physical fitness in order to feel at ease.

Don't get me wrong, I think bikes are terrific. I own several of my own, including a trendy mountain style, and ride them for pleasure and light exercise.

Once you are over 30, 35 years old, I think everyone should get down to the gym and start moving again.
