I carry my driving licence with me, in case anyone asks me my name. I
have genuinely been asked my name, and just gone blank. I cannot
remember names, sometimes not even my own.
I'm the same. I've been known to introduce people as '%person'
(pronounced the obvious way). Gets some very odd looks.
And I once had to stop and think when asked when my birthday was.
On the other hand, I can remember details of machinery with no trouble at
all. I can take something apart, make only minimal notes (say the order
of wires on a terminal block) and have no trouble at all putting it back
together. And I think the functions and pinouts of chips I grew up with
are in ROM in my brain now.
