Just a few:

- Lots of diseases which kill indiscriminately,

- Thousands of people each year feel the need to commit suicide in ways that affect others profoundly, like via train,

- Shoe and clothing sizes are inconsistent and unreliable,

- Male pattern baldness,

- Over dependence on cars for transport, which are noisy, smelly and dangerous,

- Obesity,

- We can buy cigarettes and alcohol freely, but not any decent drugs like MDMA.
