When woman is in her 60's, is it common for breasts to lose ALL firmness? Like female Dr. answer.?

Turning 63, and the last year, the breasts are just loose and not firm . I am not heavy, nevery was, but it is so horrible, a push up bra has nothing to push up. Is this the normal process of aging and law of gravity ?When woman is in her 60's, is it common for breasts to lose ALL firmness? Like female Dr. answer.?
The breasts are made up predominantly of connective tissue and fat. We know that as we age, we lose natural body fat and connective tissue can no longer regenerate or repair itself as it once did. Part of it is genetics too,
Consider yourself very lucky. It's not uncommon for a woman to lose the firmness in her breasts after the first pregnancy. My sister lost all fat and firmness in her breasts before the age of 25. She doesn't have enough fullness in her breast to fill out a bra. You're very lucky that you're only now losing that firmness but I know how dissappointing is it at the same time.
