I dread retirement.
It is 10 years away but I see it as a loss of control of my life. Right now I have my life just where I like it. A great combination of work and play. I get up every morning anxious to start work and get things done.
For me, being retired will more chores around the house, more travel (away from bike and friends), doing more things with my wife I don't enjoy that she wants to do and since I am retired, I can't tell her I am too busy.
