You can't pigeon hole the entire universe of investors into just two broad categories.
For example, I suspect that most people would characterise me as an 'older folk', but I do not need - repeat, I do not need - capital preservation (possibly my kids may want it....). My overarching investment goal is to generate a stream of income that grows as a minimum at the rate of inflation. Beginning, middle and end of story.

Modest capital appreciation over the longer term is merely a nice to have - not, repeat not, a need or requirement for me.
