I was interested in computers around age 17 (when I attended a vocational electronics school in the mid-80s), we made simple circuits and a few simple programs in Basic.

I got more interested in my early twenties, a friend of mine was a programmer and the computers an individual could afford became more powerful. (I was never very interested in Commodore 64 and its ilk, they seemed too constrained to be useful.)

I started programming in my late twenties, when I attended university and got a CS degree.

I'm not still not entirely sure that I have a passion for the hacker lifestyle. My view today is the same as when I was a teen - computers and programming can be very useful tools, but I find tools interesting only to the extent that they can help me solve an interesting problem.
