"The odds of dying from an MDMA overdose are 1 in 3.6 million. So to prevent such a dangerous substance from proliferating, it has been made illegal in all countries in the world under a UN agreement.
The odds of dying in a rollar coaster accident are 1 in 3.2 million. The odds of dying by parachuting are 3 in 1000 per year. 1 in every 500,000 skiers are killed. Every year, soccer players run the risk of 1 in 25,000 of getting killed. And the odds of burning to death in your sleep are 1 in 10,000.1
Yet no one considers banning carnivals or skydiving. No one feels that our society would be much safer if we did away with ski resorts or soccer. And no one advocates for the elimination of houses because of fire risks."
