Wimps, you call 28 C hot?
It's not that it's hot, it's the issue of sweating loads, smelling more, elderly and babies more at risk, having more showers, washing more clothes, carrying more water, people losing their temper, sticking to seats, dehydrating, more easily getting cramps when playing sports, waisting more electricity on AC's/fans, dying grass/plants, water hosepipe bans, ruined lawns, increase of wasps/bees, being stung by wasps, afternoon exhaustion, difficulting sleeping, sunburns, tanlines, flying ants, being sunblind, losing sunglasses, people fainting on the London underground, etc. I like the cold and rain, you can choose to warm yourself up. That said, 22 C sunny day is just fine. And if you really like sweating, there are always saunas!
