Men have better detection of light, depth perception, and small movement. Women have better hearing, and they're more sensitive to taste and smells. Women are more tactile. That's why men are so easily turned on by pictures. Testosterone levels are actually lower in spring.
Men speak for the public.
When they talk, they're trying to get attention. Women are private speakers. When they talk, it's to strengthen emotional ties. Men do not like change. Admit to being wrong, apologize, admit to not knowing the answer.
