What would you teach every girl on the planet about men and men on the planet about girls if you had the chance?

Men are from a very cold, dry place with low gravity and very thin air which is devoid of oxygen and full of ultraviolet radiation. Water evaporates fast. Ice sublimes directly into vapor. Spacesuits are essential.

Women are from a very very hot, dry place with nice gravity, super duper thick air which is devoid of oxygen and full of hydrochloric acid. Lead melts. Pizzas cook in 3 seconds. Spacesuits won't help.
