I am on the verge of starting a new career, late in life. I have worked many different jobs in my life, from being a soldier, to a Police Officer, to railroading, financial services and warehouse work. I plan to take the licensure exam in my state to be a middle school math teacher in May. If all goes well, next fall I will be a 55 year old brand new Math teacher somewhere in Massachusetts. I plan to work at this until I am 70...and then retire. 

The numbers to me, are just numbers. I still feel as vigorous as I did when I was 27. I train in martial arts two or three days a week and engage in some seriously intense cardio workouts involving punching and kicking things twice a week as well as running.
