If you dont mind back breaking work, then sure go for it. Im not sure what you think it is like but its no walk in the park. Most of us who have been doing it for a while hope to be in more of a managerial role when we are about your age. Im not one of these guys who are going to sugar coat it for you. At times it really can stink. You work in all kinds of adverse conditions hot, cold ,confinded spaces and I hope you dont have a fear of heights. And think about the big pay cut you are going to take. With no experiance dont expect a hell of a whole lot to start...... Just some things to think about. Personally if I was you and was in It I would stay were im at and maybe try to work with a local EC for a while on saturdays to see if its really something that your really want to do........ I personally would never hire someone based on age, I know plenty of 20-25 year old appretices that arent worth spit. And I also know plenty of 35 and up guys that I would love to be able to hire. Its all about attitude
