Jamaican men increased aggression due to wild animal DNA ?

The increasingly  aggressive  behaviour of the Jamaica men is being said to be linked to the increasing consumption of aggressive wild animals such as the crocodile.

Anecdotal information from at least two men from an eastern parish, where the eggs of the crocodile are stolen and used to make punch is lends itself to some credence that the male has become more “wicked” in recent times.

The men involved have indicated that after consuming doses of this punch they have noticed increased levels of aggressive and violent behaviour. They stopped consuming the punch for a while, noticed a drop off in the level of aggressive but once they resumed consumption of the punch, the level of aggressive increased exponentially.

Both men incidentally have stopped consuming this punch, with one man heard to be saying  “ dis ting ting tun u into a beast. Worse the kids from some of these guys are themselves behaving like beast”.

Is there a doctor in house who can determine if there is any scientific or medical evidence to support this claim?

This would be rather interesting and begs the question, are Jamaica men become like wild beast?
