The most consistent, enthusiastic exercisers are those who do activities they like, whether it’s dancing, hiking or aqua aerobics. Exercise has a strong, anti
effect on cells’ DNA. It influences telomeres, “caps” at the ends of DNA strands, kind of like the tips on shoelaces, which protect chromosomes from destruction. Telomeres shorten progressively over time, leading to cellular damage due to the inability of the cell to duplicate itself correctly.
