Do you have anything to back up these claims? They seem outlandish to me. For example, there are plenty of African migrants in Europe. I've never heard anything about a vastly reduced life expectancy. There are some small dietary problems they might have if they switched to local food and drink, but I would have thought that their immune system would adjust over time.
