Do Thin/Bony People Dent Mattresses/Soft Things More?

Not true. Even though you weigh less than your mother, you may have more muscle and therefore, more m. Pound for pound, muscle has more m than fat. This is why muscle burns more calories. Weight isn't what matters, but m. I am heavier than my mother, but I wear a size 6 skirt; she wears a 10, even though she is lighter than me. This is because my mother has a higher body fat percentage and lower m than I do; I have a higher muscle percentage and because of that, I also have a heavier skeleton because I'm absorbing more calcium due to having more muscle m, but because muscle is compact, it shapes and contours to your body, whereas fat tends to be bulky and hang off the body. Your high muscle m and heavier skeleton is the reason you tend to leave indentations and imprints.
