Welcome Niclin! My "workouts" are pretty modest, some early morning walking and a short sprint but I do feel better for them and of course not constantly wanting to drink or being hungover is like losing a ball and chain.
Good luck on the job front Manta.
Warm in London. The daytime is fine, I like it but nightime is either closed windows and too hot or open windows and too noisy. Air conditioning would be great but I could never justify the cost for the couple weeks a year maximum that it would be useful . Us penguins can cope.
