Siegfried Hekimi, a biology professor at McGill University, says he is impressed not only by the fact that Ikariots live longer, but that they also look much younger. Their younger appearance is what seems to predict whether they will live longer.
As we get older we are ravaged by the loss of homeostasis, the ability of our body to restore a functional, stable, internal environment. “This gradual loss is also what kills you when it becomes very severe at an old age,”
When people look young for their age, it means their rate of loss of good homeostasis is slower than average, he continues. “Which suggests it will take a longer time for the processes to be so degraded that they will kill you. Thus, the logical conclusion is that, on average, people who look good for their age will live longer than people who look worse at the same age.”
