I strong suspect that only a certain percentage of people can easily follow the "just suffer and you will adapt" advice. I mean believe some can do but I wouldn't take this as universal advise. Edit: Extreme reactions to cold even have a name, Raynard's syndrome[1]. But as someone who suffers occasionally from this, I think it's more useful to say people's cold reactions vary.

...just like that first sunburn of summer let you enjoy the rest of the summer sun without burning.

Advise that even more clearly applies to only some people and some locations.
