Maybe I’m misreading something in the tone, but when unusually sensitive people should consider maybe changing their planned a activities a little bit what does that mean for the average healthy person? It kind of sounds like a non-warning. I mean what’s prolonged exertion anyway? A marathon? 10 hours of physical labor like construction? A light jog in the park? And what is “reduce”? Stop completely? Switch from marathon to half marathon? Work a 5 hour construction shift instead of 10? Somehow I don’t think physical laborers are reducing their workload for this.
