"How many years am I demonstrating using the visual medium of my aging face?"
12, at most. Then again, it's hard to tell when you can't see any facial features. :P
I thought it mean how many years you've been showing [people how to do things]
Thankfully it was "anni" with double "N", or we'd have a whole other series of comments. 20Feb17
Why "How old do I look" is not a correct answer? It seems the same meaning to me.
this is one of those awkward questions like "do i look fat in these jeans" lol :p
According to the rest of their logic, it really should've been "how many years do I demonstrate?" ;-)
Like the spanish equivalent, "Cuantos años demuestro?" It translates more directly to "How many years do I show?" In terms of a proper translation, it would be "How old do I look?"
