Scientists have agreed that there is a kind of gene which results in people’s violence who were ill-treated in their childhood. This could help to explain why some people who once suffered from miserable childhood are able to lead normal life while others become violent. But another argument was raised.
It was reported that one form of a gene in people’s brain made it more likely for them to turn to violence—but only when they have undergone cruelty in their childhood.

The city has created an elephant sanctuary so the animals have a place to go instead of roaming the streets. In recent weeks it has turned into somewhat of a local tourist attraction. School children have flocked to the vacant lot for what might be the first time to see a live elephant. So far the elephant rescue program has been a success. Fift
