Problems, yes. "Biology is going to kill me soon" shouldn't have to be one of those problems, and in fact I think it makes us all slightly crazy in different ways, from not caring about the future to unscrupulously believing in afterlives.

I suspect you indended to reply to the sibling comment https://news.ycombinator.com/item?id=47827905 which contains the word "problems" rather than my comment which does not?

No, I was disputing "mortality" while agreeing with "challenges", which I've written as problems in the nice sense of "please let me finish my problem". That's some historical figure's alleged last words, I think.

(Edit: probably an embellishment of Archimedes, supposedly saying to the Roman soldier who killed him, "do not disturb my circles!" - not exactly a plaintive attitude about mortality, more just being a grumpy geometrist.)
