People that look younger than they are, live longer.
Scientists from Denmark studied 387 pairs of twins in their 70s, 80s, and 90s and found that just looking at someone’s face is enough to tell if a person will live to an old age or not. In other words, if a person looks younger than their actual age, they will live longer than a person who looks older than their actual age. And scientists have proven that it’s programmed in at the DNA level. Key pieces of DNA called telomeres, which indicate the ability of cells to replicate, are also linked to how young a person looks. So people who look younger, have shorter telomeres.
