"From 10AM to 4PM are the most dangerous hours for exposure to the sun."
The first two don't make any sense. As for SPF, the FDA minimum is 15 but the recommended minimum is 30. 10AM-4PM are the peak sunlight hours, generally (unless you live in Antarctica of course).
Tolerance can in fact cause an overdose, because the greater tolerance you can get the more of a certain substance your body will need eventually leading your body to take more than it can handle leading to overdose and death.
