It is not the young man who should be considered fortunate but the old man who has lived well, because the young man in his prime wanders much by chance, vacillating in his beliefs, while the old man has docked in the harbor, having safeguarded his own true happiness. (Epicurus)

I suppose there is something in this, but it depends on what you consider “living well” to be. Personally, I think it important to keep ones mind young and open to new ideas, if you can remember what they are. I met a 95 year old lady the other day, who plays bridge and tennis, has a computer, an i-pad and and up-to-date cellphone. She is very well informed on every subject I launched upon, goes out to concerts and plays, and looked as if she would comfortably outlive me. She has “lived well”, but in her case she has “docked” at no harbour. Good for her. Some people who dock at the harbor damage the jetty or just sit there drinking whisky and complaining (yes, I know – I make a point of complaining on this blog. I own up, guilty. I said I was an Epicuean; I never said I was a good one!).
