I'm Rob Elfferich, 82 years old. I was a civil engineer for 8 years after study. Then I turned to screenprinter for 25 years. After that I was following my hobbies after retiring. I was a chef for 6 years and I was bringing children and elderly people with brain or physical problems to places where they were during daytime. Then at the age of 74, I stopped working. Now I make graphics and more.
