Question 1

all human have sick?

Accepted Answer

Yes: Everybody has something. There are no perfect adults, and no perfect children. Sooner or later, everybody gets sick. Luckily, our bodies have miraculous self-healing powers, and we generally get well. For the unlucky ones among us... well, those don't make it. The lesson here is to do kind and meaningful things each day, while we are still in good health.

Question 2

why do human wants sex?

Accepted Answer

Simple evolution: In a village far, far away, and a long time ago, some humans wanted sex. Some humans didn't want sex. As the years went by, the humans who wanted sex got pregnant more often, had more children, and became the great majority of the population. The humans who didn't want sex didn't have many children, so those carrying the "don't want sex" trait became a smaller and smaller part of the population.
