If I fly from Chennai to London&return immediately back to Chennai,will I have jet lag (same time zone)?

Get into your new time zone, rather than think of what time it is in Vietnam. Drink fluids to hydrate and stay of alcohol, after a day or so you'll be feeling better.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
