With thanks to @daniel for such an important share:
The threshold for survival in heat is lower than we thought: a Wet Bulb Temperature of 31°C, not 35°C, might kill a healthy young people in a few hours.
This kind of research is essential not only for stimulating info-sharing on survival strategies and other forms of mutualism in society, but also for pushing harder for prevention. We do not have to go gentle into this suffocating coming day.
@MLClark @daniel Check out the experimental Wet Bulb Globe Temperature calculator from the National Weather service.

@MLClark @daniel The locations marked by red and darker orange dots on this map already exceed 31C WBGT.
