Its the same in Britain as well. But in other places its not as strong, in Spain for example the is a much larger amount of mixing and it took much longer to happen.

Specially his recent lectures on India are brilliant. [1] [1] https://www.youtube.com/watch?v=pra7YZWVc-s https://www.youtube.com/watch?v=pra7YZWVc-s
