Or it might be that, if we measured all the responses simultaneously, we’d find that mounting a protective response to radiation made us more vulnerable to infection, alcohol, and all the rest.
Or maybe it would just require the expenditure of energy.
And yet anabolism and expenditures of energy pretty reliably shorten lifespan. Many of these responses rely on the use of regulatory RNA; and the dicer-mediated siRNA mechanism has been shown to have a limited capacity that degrades when multiple regulatory responses occur simultaneously.
