I manage an apartment building; one of the tenants has peripheral neuropathy. - something like that. The prognosis isn't good, I understand, but he still gets around OK and is a nice guy to have around. Not sure how old he is- maybe 60 - and he has had it for some time. I have never asked him whether he is diabetic.
It seems to me that it is an ailment that should be curable before too long
