In some ways I envy you.
I wouldn't want to be 70 years old, but I think I would have loved to have been young when you were young. The fact is I feel totally alienated from my own generation (Gen X); I always have. Almost everyone I know in my own age bracket is addicted to drugs and functionally illiterate.
I can do more than imagine how much it sucks to be seventy years old. I grew up around my grandpa and his siblings so I know what old age is like. But even so, you should feel proud to be a member of your generation, for it is, so far, the most privileged generation in history; and not just in terms of prosperity and overall happiness, but in what you were able to see happening right before your eyes (like the Apollo moon landing).
