- scurvy 10y ago30 minutes a day causes cancer? What did we ever do before long sleeves? Must have been an evolutionary miracle!
- mikestew 10y agoWhatever did we do? One possibility is that "we" got skin cancer at higher rates than we do now. Or at least we would have had we lived much past the age of thirty. And that's just one possibility that sprang immediately to mind, I'm sure there are others that are more sound were one to give it more than the brief milliseconds of thought that you and I obviously did.
- taeric 10y agoYou do know that thirty was limited mainly from infant mortality, war, and complications in childbirths, right? In particular, men could live a very long time. Often did.
- tominous 10y agoNot necessarily; see radiation hormesis [1]. Small amounts can be beneficial even if large amounts are harmful. We also know there's a link between more sunlight and less incidence of other types of cancer. It's still unknown whether this is mediated by Vitamin D or other mechanisms.
