Can we slow the aging process?
Ask the doctor
Q. Is it possible that scientists will one day be able to slow down the aging of our bodies?
A. You may be dubious, but yes, it is possible. I know it seems that every living thing ages — the flowers in the garden, our pets, and us. Yet a Harvard Medical School colleague who studies aging, genetics professor David Sinclair, tells me there are certain cold-water fish that may never die natural deaths. They die from injury or being consumed by a larger animal, but it's not clear they die naturally. Some are hundreds of years old, and still frisky.
