I think for me it's the idea of getting closer to retirement, so my risk avoidance is pretty high. I would love to see the 15-20% but I am pretty gun shy after witnessing what happened to some friends who were within a year or so of retirement back in 07-09 financial crisis who lost so much in that drop that they had to stay on a few more years until the market recovered. I know money is important, but IMO time is more, and I don't want to lose even a second of what I plan to do in retirement while I wait for a drop to recover. I realize over time it will and my thinking may be wrong but that's my 2 cents. I have an ideal number I would like to reach and I'm close enough not to gamble it.
