I have visited Bern many times, and find it quite a nice, charming city.
Perhaps besides your Yoga angle check into their running club there. They have some of the most wonderful paths around the river and some challenging hills,
false flats, away from it.
Running is a great equalizer that brings people from differing backgrounds together. Oh yes, playing music with other people, perhaps an even larger equalizer, in my humble opinion.
But for sure it will be a big change from LaLa land, and hopefully you will embrace this and are ready for the new dynamics of the wonderfully
human European mind-set.
