Even then I felt it the right decision to continue, guess the thing we really want to catch is a subtile incapacitation where the other guy just freezes...
Indeed, there are quite a few sufferers of epilepsy who do not know that they have epilepsy because for them it does not manifest in the familiar shaking on the floor type Grand Mal seizure but instead they only suffer from "Absence Seizures" where they, effectively, zone out for a period of time, oblivious to the world around them and afterwards are often unaware that it had even happened, much like microsleep.
And, of course, epilepsy can develop in a previously healthy person at any time.
