My boss nearly collapsing and being driven to the hospital WAS. And they are keeping him for more tests. I am almost sure their stated reasons are code for 'shit, we don't know what's wrong, but he looks too bad to let him leave."
I really like my boss. I can give myself panic attacks by thinking of him leaving for some other job (I am pretty sure my department would crumble down around our ears without him).
So, yeah, today was rather .... odd.
