Which decision paid off only after many years, when its value could not yet be proved?

there was already an area of research, the autonomic nervous system, which was relatively neglected. It was between cardiology and neurology, and these areas in between are often the province of neither specialty, and so can lag behind. And that was the area I chose and this changed the second half of my life, if you like, because I then set up a laboratory.

I was fortunate even from that point of view because I got a very good research collaboration agreement with Upjohn, the American Upjohn company. So that could help me to go on with my research.

I would like to have been concerned about this existential threat sooner.
