> Travelling is still utterly exhausting
I found that this is mostly the case if you have to change a lot like you do when you travel by plane, especially getting to and from the airport is exhausting. When I travel the same route by train I feel that it takes a bit longer, but I arrive much less exhausted. I think it's because I don't need to wait anywhere, I can stand up and walk around, I can sit down and use the computer with Internet, there is way more space and when I change I can get something to eat and drink.
I'm traveling from Varberg in Sweden to Burgpreppach in Germany which are both fairly small so it takes a lot of time and effort to get to the airports. But both are really close to train stations.
