I wonder about selective hearing which some men have in plenty. My beloved had early bowel cancer 3 years after my diagnosis - surgery and elected to have chemo (very wise). But every symptom was like a revelation of something unknown and totally unexpected! "My feet feel like I have 2 pairs of socks on!" - ah, yes that would be the peripheral neuropathy I have had (almost couldn't walk) for years. Metallic taste, nose problems, and so on. And he kept his hair!! I have accepted that some people can only identify in the first person. Apart from the action with a heavy blunt object (too extreme!), there is no cure as far as I know. You have to accentuate the positive!
