COVID. For >70 y.o. individuals mortality rate is 30%. If you're >70 y.o. have heart condition and have diabetes (all risk factors) COVID is clearly more deadly than some (most?) cancers, not to mention it kills in the order of weeks, when cancer kills in the order of months or years.
Where are you getting this number? It is significantly higher than any I have seen.

Right. OTOH in the Chinese treatment guidelines, they say not to give it for >65 y.o. Unfortunately that's exactly the population it would potentially benefit the most. I'm guessing there must be some reason that's in there, but I'd like to see numbers.
