We're in a Utopia. Utopias destroy purpose. Without purpose intelligence can not exist, so the rate of apoptosis surpasses the rate of reproduction. Obesity is a symptom of this, not the cause.

> According to Calhoun, the extinction consisted of two stages: the “first death” — characterized by the loss of purpose in life beyond mere existence (including the loss of desire to mate, raise young, or establish a role within society) — and “second death” marked by the literal end of life and the extinction of Universe 25.

> "Males who failed withdrew physically and psychologically; they became very inactive and aggregated in large pools near the center of the floor of the universe. From this point on they no longer initiated interaction with their established associates, nor did their behavior elicit attack by territorial males," read the paper. "Even so, they became characterized by many wounds and much scar tissue as a result of attacks by other withdrawn males."
