Sweatting
Yesterday my girlfriend and I took a day and visited a thermal bath, Bad Radkersburg.
It was a quite relaxing day, I also tried the sauna and steam bath but I didn't like that part very much.
Nevertheless I can imagine to do it again somewhere in the (far?) future, because my girlfriend likes it quite a lot.
The only bad point in the whole was that we had to drive almost two hours in each direction to get there.
