Not that guy, but there's heat waves which, when combined with high humidity, go near or even above the "wet-bulb temperature" which is a point where evaporation cannot cool you down anymore (goes hand in hand with high humidity).
There has been plenty of cases where temperature/humidity reach dangerous levels, even for normal fit young people:
