Michel Houellebecq said this quote

Contemporary consciousness is no longer equipped to deal with our mortality. Never in any other time, or any other civilization, have people thought so much or so contantly about aging. Each individual has a simple view of the future: a time will come when the sum of pleasures that life has left to offer is outweighed by the sum of pain (one can actually feel the meter ticking, and it ticks always in the same direction). This weighing up of pleasure and pain, which everyone is forced to make sooner or later, leads logically, at a certain age, to suicide.
