I think in the UK, because people aren't used to those temperatures, it can be quite a bit more deadly at 100F. I*'m acclimatized to the heat, but I know what to do to stay safe, because it's been a way of life. Stay safe and stay hydrated.I love that. Speaks so well of how I've been feeling over the last few days. Just on the 100F here so doesn't measure up to some of the US but hey, we are just not used to it.
