Things shown in video are 100% true but they are the best ways to live in both .If you try to live like a German guy or by following the german rules in India then you can't sustain (because of high population u can't control each and every person) in the same way you can't follow the Indian rules in Germany(cops can simply find out the person who is not following the rules in fewer people).
BTW Indian guy can adopt any living style very easily,there are too many Indians who are living in Germany,USA,UK and Arab countries (where teasing a woman can cost you a life).
I think Indian way is the best one to live in India,you can sustain here by following those rules only.
