In the country of plastic surgery, faces can be so beautiful, not to mention legs. I believe some of them are true, but only a small part, most of them are cosmetic surgery, and there is a price to pay. People get sick when they get old.
In a big sports country, moderate exercise every day brings people not only beautiful legs, but also more curves, but you can't practice with your eyes closed. You'd better consult and practice again. Health and happiness will always accompany you.
