I'm perfectly sane. You have to realise that we all feel the temperatures differently. I've seen people in winter coats in 28c heatwaves. Likewise I've seen people in t shirts and shorts in 3c
Once winter is over, even the slightest sniff of high pressure sends the temps soaring thanks to humid crap from europe. IF we could get sunny days, with average temps, then I'd welcome them. Nothing against sunshine, but can't stand above average temps. I feel warm at 12c, very warm at 18c uncomfortable at 22c and physically sick at 25c or above. Be thankful you have a body that tolerates warmth, because I wish I did.
