A few weeks ago, I witnessed a (grand-mal / tonic-clonic) seizure while I was coming home on a train. This was the first and only one that I actually saw “in real life”.
I had no idea how to behave or what or when should I do it. I had the theory in my head, I knew the entire drill. But all I could do was to watch as others helped the guy seizing.
Have you ever been on the other side?
