Apparently you don’t live in Scotland (west coast at least). Spring may not be warm, but we get some clear dry days, and if you’re in the sun and out of the wind you can feel the heat. By summer it’s so muggy and humid that 15 degrees (Celsius) feels oppressive. I used to live in Australia but the (not-)heat here feels worse.
Having a cold shower at the end is probably number 1 if I made a list of things I do right in life that most people don’t do. I feel so clean and comfortable for ages afterwards, no matter if I’m in my house or the middle of the forest, summer or winter. Best thing my dad ever taught me. (I mean he’s still alive, so technically ‘best so far’, but I’m not holding my breath).
