People will need to travel not only for "vacations", but for works, for coming back home to their families.
40 years ago, only business man travelled around the world, now youngsters are going to the other side of the world just for delivering capuccinos.
It will take time, for sure, even the production of a vaccine.
But from that day people won't be scared anymore by knowing to be immune to the virus.
Of course it's an optimistic scenario, nobody knows what is gong to happen next.
We can only hope for the best.
