In the future, I can imagine that we will genetically modify ourselves using the genes that have doubled our life span since we were chimpanzees.

Our grandkids will lead the lives of the gods of mythology. Zeus could think and move objects around. We'll have that power. Venus had a perfect, timeless body. We'll have that, too. Pegasus was a flying horse. We'll be able to modify life in the future.

When you extend life span, that's really something. That's hard to do.

The key to the future in an aging society is not found in increasing just our life span; we need to increase our health span at the same time.

Retarding the aging process would be therapy and enhancement because it would mean defeating diseases and because it would extend our life span.

In one century, we've added 28 years to our average life span - a change so rapid that our brains couldn't possibly have evolved to accommodate it.
