Awesome article, but I'll continue to document.
The documentation will come handy when you are 80 and have nothing to do but look back at your life.
Sure, there are people who would just sit there and do nothing, but anyone more creative should not see the age as a show-stopper. Couple of examples I have at hand, my father and my uncle, both around the above mentioned age, but fairly active in their fields (science and architecture). Not that they need to do it, they have already earned their fair share, it's just that they simply enjoy doing it. As opposed to sitting and doing nothing...
Anyway, my point is, why 'document' while you're young and then try to 're-live' the experience, if you could 'enjoy' while you're young and do something else enjoyable when you're older?
