The "mole" grows continuously on the waist, and the three "big moles" are very neat. What does it stand for?

The mole itself has no meaning, but the skin is dark and pigmentation increases. And people with more moles can live longer. Scientists from King's College London conducted a comparative study of more than 1800 pairs of twins, and found that people with more moles (more than 1000) have longer telomeres than those with less than 25 moles.

Telomeres are the terminal structures of chromosomes. As cells age and lose their ability to divide, telomere length will gradually shorten. Therefore, the longer the telomere, the slower the cell aging.

However, it is worth noting that moles are easy to degenerate after frequent rubbing, especially those on the waist, which are often rubbed by clothes and may mutate. Moles will proliferate indefinitely after malignant transformation, and may eventually grow on your face. So keep an eye on it, and you'd better get rid of it.
