Is web development for grown ups?

Lately I've been thinking about my future in the business of web development. I'm now 32 years old.
Maybe it's just me, but I find it hard to imagine a serious 50 year old dude writing javascript for a living. I can imagine middle-aged doctors, hardware engineers, lawyers, accountants. For some reason, I can't imagine the same for web developers. In most companies I couldn't find a web programmer over the age of 35. So what do you think - is web development for grown ups or not?

Beer and coding? I thought programmers are organisms that employ natural processes to transform caffeine and pizza into code.
