listen, i don't doubt this, and i don't think serious complications are likely.
personally? i'll pass.
but, i'm not 75 years old, and i'm not diabetic and ...
if i were? i think i'd be a little more risk adverse, and willing to take a chance - and pretty pissed off at anybody telling me i can't, for my own good.
there is always some minimal chance of complications, but i wouldn't expect a high chance of serious ones.
i will say this, though: you'd better hope it doesn't mutate. that's a far more serious concern...
