This quote emphasizes the correlation between exercise, stress, and telomere length, highlighting the importance of physical activity and stress management for maintaining cellular health.

For me, arguably the story of telomeres and telomerase began thousands of years ago, in the cornfields of the Maya highlands of Central America.
If we think of our chromosomes - they carry our genetic material - as being like shoelaces, I work on the plastic tips at the end that protect them.

When I go to my health club, and it's in the basement, you have to take the elevator down. And this drives me crazy. Why can't there be a stairway? At least make it as easy to exercise as it is to not exercise. It's in society's interest for me to take the stairs.
We have to ask ourselves whether medicine is to remain a humanitarian and respected profession or a new but depersonalized science in the service of prolonging life rather than diminishing human suffering.
