In the Netherlands, where I am from, at least (I think it is less so in the US?), you are a complete failure/loser if you are a coder > 35 y/o (I am 40). You are supposed to be a manager then. My path was different than that but I cannot help thinking this attitude which is pushed in university and by (a lot of) parents influenced some decisions I made. Coders over 45 are considered sad and when you meet them in companies they are usually in the basement and treated like idiots. We were hired to give this mobile app development course to a large company in the Netherlands; it turned out this was just to fill out the training responsibilities the company had with their employees. All of the trainees were over 45, most over 50 and the company didn't care what we did and they would never use it there but apparently their employees expressed interest to learn about app development. Sad.
