Not worth being 70. I'd rather be working and know I have more than just a few years left until I'm 6' under. Enjoy retirement or as it's better known "the last stop before death".
To be truthful, the only reason I ever worked was to make money and pay the bills. I never liked working. I liked socializing at work, but hated all the bullshit office politics. I think I was just biding my time until I could retire one day. Work is highly overrated, IMO. These days, I volunteer. It is better than work. And I can stay up late and sleep in all I want.
I retired a month before turning 65, after working for more than fifty years, counting summer jobs as a teenager. Fortunately, I invested wisely enough in my future that I can well afford retirement. I am very healthy. I get to the gym much more regularly than I did when I worked. Of course I have no idea when I will die, but I am guessing it is going to be awhile before I go. So this may be the last stop, but it is a great stop with lots to do and see.
