Until recently i was a third year apprentice with 5000 hours completed along with the required 375 hours of code class. I had a little less than a year and a half to go before I got my license. Although I nolonger work in the field Im 48 and had very little if any problems doing the work its self. Find a reputable contractor to work for and you should be fine. Just be aware there are more trip and falling hazards along with electrical shock than you can shake a stick at. I also found out that most contractors do not offer any kink of health insurance so this may be a issue if you have kids. Best of luck to you,
