two requirements to have a killer
body. First, you must be attractive such that the vast majority of normal people would agree you are attractive. Second, you must on account of physical conditioning, strength, stamina, VO2 max, and flexibility look like you are capable of beating to
death, using only your body as a weapon, the vast majority of other people who are in your sex and age group and who are close in height.
