Merten Gareiß is driving trucks – for example together with heart surgeon Markus Studer.
In an eMail to Wolfgang Ellenberger he writes:
With Markus I was driving just one week, and I have driven 4 times with the Spitzbart company (3 times with Lisi Rott, once with my wife as co-pilot – but she did not drive. In plus some rides with the busses of the Wachter company. After an operation of my shoulder I stopped this activity.
Now – besides the medical profession- I am only acting as amateur actor as since 2003, see www.spielfeld.org
