When it comes to skills, there are a bunch of (imo) basic skills that most people got covered in life sciences. Sometime there are those special skills that you can't learn in any lab that are interesting, that is true. My MSc was in an obesity related area which is one of those areas that do need loads of research because we are getting FAT. I am not bored of it, I am just bored of the city, that is why I left. During my travels I really liked Berlin. And had Heidelberg and Freiburg in mind because they have many students. the city I live at right now caters to business people and is way too expensive and snobby for me. The brain is still a mystery to us. So this could also be an option. I haven been interested in psychoactive substances lately, but will probably not be able to find a lab that is doing molecular biology research with MDMA etc., they are very rare.
