Healthy lifestyle is important to minimise the disease symptoms/manifestations but its the small gene pool which is originally responsible for such dieases being acquired by many children born out of Qatari nationals.

Government provides incentive to Qatari males if they first marry a Qatari female and that's the reason all males here would first marry someone of their distant cousins.

I wouldn't be surprised if dieases like diabetes, obesity or high blood pressure etc. continued to increase amongst the youth in the future.
