I see a couple a posts about the youngest people in here, and that's great what these kids are accomplishing. But I'm wondering who's the oldest that does this full time, to get an idea of an average career lenght that I can expect (Being that I stay Healthy). I'm 26 running my business for almost 6 years, was about 14-15 years old when I started working for my Brother in law(BTW, he's now cutting 370 accounts a week, damn!). I get tired sometimes in the middle of the summer, wonder how many years I can do this. i do love my job, working outdoors in ALL the elements, how do you hold up later in life in this field?
