On the M49 this morning, the matrix board had a message saying "extreme heat, take care". It didn't tell me how to take care though, what to do, how to do it, how I could avoid dying etc. All very disappointing.
Then on the A470, the matrix sign said "Heat alert, take water with you". It didn't tell me how much water or where to take it. So confusing. Surely taking water with me would be heavy, which would make me hotter?
I tried the trick last night where you put hands in cold water. I guess it worked as it did make my hands colder, for a very short time anyway. Other than that it was useless.
