I have been a county agent for the past 13 years and was a vo-ag teacher 10 years before that. I've spent my career advising others what to do to have healthy lawns and landscapes and when I retire I plan to start my own lanw/landscape business. My question is: I will retire when I'm 57 - can I physically start this type of work? Are there any of you out there that are in this situation? I'm in good health, reasonably good shape (need to loose a few pounds) However , the county agent work is not exactly a heart pounding occupation.
