True or false

1. Is it true that a big animal like an elephant is hard to kill because it has a thickest skin in animal kingdom ?
I always think if one is not selected as the best fit for survival will die out in the next generation.

2. Is it true that there is a definition of mental raping invented by neurologists ?

3. There are geneticists who can't do jobs of a cell biologist because they just never learn about cell suicides ?

You don't see that once someone has got a money generated tool behind his/her back, he/she will always laughs/smiles even when she is cleaning the dirtiest public toilet out there!
