Had that happen at work in the late 80's. Guy pulls up on his mc, drops the kickstand then keels over, off the bike on to his head. Clearly a seizure, i'm trying to get a stick in his mouth while 1/2 doz people incl co-workers are standing there. Someone call 911 as they're watching. Once i got the stick in his mouth i ended up calling them. This is why there's 10-20-30 people standing there now a days taking videos of someone being stabbed or sexually assaulted instead of jumping in.
