I've been for walk today in Chester city centre and most people are wrapped up with coats and scarves in the cold weather (it's about 5C). But I've seen a couple of guys wearing just a t-shirt, and another guy wearing a coat but with shorts. Are these people just immune to cold weather or is it a machismo thing?
EDIT: thanks for the replies. It's interesting to understand how some people have difficulty regulating their temperature, sweat easily, or just don't feel the cold so much. I will feel bad for you come the summer…
