A lot of people are living in a dream world - they want to deny that aging occurs or believe it doesn't have to occur. They'll hold on to this belief until the moment they die. The reality will eventually hit them.

Exercise is roughly the only equivalent of a fountain of youth that exists today, and it's free to everyone.

How long you live is less important than how healthy you are along the way.

If you do an autopsy on an 85-year-old who died of a stroke, you will find five other things that person was about to die from.

If you can slow the biological process of aging, even a minor slowdown in the rate at which we age yields improvements in virtually every condition of frailty and disability and mortality that we see at later ages.

In Genesis 6:3, it says man can live to be 120, but there is no scientific basis for it.

The last thing you ever want to do is extend the period of frailty and disability and make people unhealthy for a longer time period. So lifespan extension in and of itself should not be the goal of medicine, nor should it be the goal of public health, nor should it be the goal of aging science.

Exercise is roughly equivalent to an oil lube and a filter for a car. You don't have to do it, but when you do, it makes the car run a lot better.

Once DNA acquires the ability to persist forever, the carriers become disposable. Essentially, our bodies are designed to last long enough to reproduce.

The vast majority of studies say anti-aging supplements don't work.
