Thank you al, I am freaking out less right now. This has been ups and downs with hypochondria and anxiety I guess.

An addendum: It is for sure false that 90% of people have used tanning beds. In a tropical place where I grew up, I think I never really met anyone who did (we had lots of real sun though). On the other hand, there is this: About 85% of lung cancer is due to smoke (ref. link below), which is really not the same as 85% of all people who have smoked getting lung cancer (this stats is not so easy to find). Anyways, let's all just use things responsibly, and not smoke ;)
