Belly buttons are just a social construct

So is that dead white male “gravity” shit…

The authors—Edward Jones of Howard University and Adrian Bejan and Jordan Charles of Duke University—attribute the two trends to a common factor: center of gravity.

They explain:

Anthropometric measurements of large populations show that systematic differences exist among blacks, whites and Asians.

The published evidence is massive: blacks have longer limbs than whites, and because blacks have longer legs and smaller circumferences (e.g. calves and arms), their center of mass is higher than that in other individuals of the same height. Asians and whites have longer torsos, therefore their centers of mass are lower.
