I know most women are afraid of rats.Why are some men are afraid,too?

A very few number men may be found getting afraid of rats or reptiles as like as women, whereas, some women claim that they aren't afraid of even snakes or tigers. men getting afraid of rats etc. and women not of even snakes are just odd and peculiar cases for the both. I've a wise old friend who says often in light vain (jokingly) men that scared of rats are almost 'womanish', lacking their masculinity and women not scared of even snakes etc. mostly loses their femininity, whereas, both the cases contain oddity and peculiarity. Further he said, "notwithstanding, a real woman should continue with their femininity and men their masculinity, that's much. Otherwise, life and living with such people seem artificial, not natural in reality, hence that nature living becomes charmless to most people." With regards, ARShams
