Longevity is not the meaning of life
So you want to live forever? Excellent. You’ve come to the right place. Here at Gilgamesh-Makropulos Limited, we know a thing or two about immortality. First, we need to track your metrics: biological age versus chronological age, average number of erections per night, metabolic health, maximal oxygen consumption, heart rate variability, stool volume and color and salivary flow rate. Sound good? My assistant will fetch the paperwork. This might seem like the beginning of a potboiler sci-fi rip-off. But it’s actually closer to our reality than Bernard Williams would have liked. While we still haven’t achieved immortality, the cult of "longevity" has become something of a gold rush in recent years.
