As of Christmas 2016 I have removed the remaining content of my Homepage. The contribution to mankind was negligible anyway. I have also changed both email address and cell number. If you can not get in touch with me anymore, you can still reach me via Xing, LinkedIn or Facebook. And I still live in Gerlingen, if that is of any help to you. Sorry for not putting out more information, but nowadays everyone should be careful with sharing address data on internet pages.
