I was living for a year in Asia while I was doing my first PhD.

They are amazing. The differences of culture are unbeatable.

I China for example even if it was 3 years ago that guys wasn't wondering if they forgot their wallet at home.

Their personal problem was not to have enough battery at phone. Same in Japan.

In India the inflation is so bad in some regions.

In Iraq you are not even using money in the conflict regions.

About Europe, I am French. We all love money in our hands.
