Why?
It is young people who should be more careful. The micromort idea is a helplful way of thinking about this, where one micromort is a 1 in 10^6 risk of death. A young man massively increases his risk of death by buying a motorcycle or scuba diving, since his risk of death is very low to begin with. at 100, your risk of dying in any day is so high, that you barely affect your life expectancy by taking up a dangerous pastime.
