Waaay too late for that. I mean the die young part.
and we have missed you
Hope you are well, or at least getting weller (-ish)
I'm glad you are back. The place is less lively without you. 
It is good to see you active. Keep fightin'!
I'd be kung-fu fighting but [whispers] Ninjas are watching.
Very sorry to hear that -comas, seizures, yikes. I hope the cause is something that can be fixed with medicine or surgery. I hope so. Take care of yourself.
Why thank you, steamed. That's really sweet. My best to Fhuff.
Wow, that really was nice. Who knew steamed was in favor of health care? 
My dear frop & crabbs, I will survive.

In celebration, may I suggest a GIF game, based on the words 'coma' and/or 'seizure'?
Gramps
I didn't realize that you were unwell. I hope you are doing better. Remember only the good die young.
