not just higher cancer rates, but higher rates of all kinds of aging-related deaths
the advantage of being warm-blooded is that your metabolism is more precise and much faster, but, as james dean quoted willard motley saying, 'live fast, die young'
(being old is a more important risk factor for cancer than anything else i can think of, even smoking and radioactive fallout)
small sharks around greenland, to take an extreme example, are at essentially the temperature of the seawater, about -1.8°. larger sharks could conceivably raise their internal body temperature, but greenland sharks swim very slowly to avoid this even when they are large. so their metabolism is about 16× slower than yours is—both healing and aging processes happen slower. their gestational period is about 8–18 years
Thank you. This is the kind of thing I was looking for. After posting, I also found out that plants are even further in the other direction because their strong cell walls prevent metasticization.
