10 minutes of sun per day is typically less likely to give you cancer than 0 minutes. Vitamin D (and other compounds involved in the synthesis from cholesterol that you won’t get in supplements) upregulate DNA repair polymerases that protect against carcinogens. Of course after a few minutes the costs of UV exposure outweight this benefit though.






I find it difficult to imagine a future in which humans aren’t making fun of impaired cognition.
I think the context is what’s most important, if anyone actually directs such language (be it retarded, idiot, etc) towards people with genuine mental impairment, that constitutes a slur. But the word ‘retarded’ literally means ‘slow’, and is still regularly used (including by myself) in scientific and technical contexts (compared to racist or homophobic slurs, which are only ever really used in a ‘slur’ kind of way).
I wouldn’t really have a problem with calling people ‘slow’ in jest, and I don’t think many would. Imo if not ‘retarded’, it’ll be something else with the same meaning.
