As someone who does not live in a climate controlled home but occasionally stays with people who do, I wholly disagree. I love being able to breathe and think rather than having to be in a place that's just 7-10°F colder because of a lot of effort airing at the right times.
To be fair, exposing yourself to the sun is unsafe. During summer the rule is: Don't go out into the sun. If you have to go into the sun, cover yourself with clothes. If you can't cover yourself with clothes, wear sunscreen. And limit the sun exposure to an absolute minimum. There is no safe tan.
The basic two-step human respiratory process completely baffles anon. He regularly forgets whether he should inhale or exhale. Anon is well known for tripping over stray dust particles.
