Agreed. As people get older they generally need to become more risk averse with their retirement funds. But at any given age, people that have more money still tend to be less risk averse. As you say, your concern was that you'd be concerned about not being able to make back losses and having to go back to work as a result. But if you had enough money saved that you could put a portion of it into conservative investments to preclude that, you'd probably be willing to put the rest at higher risk so that you have the potential to enjoy a fuller retirement. Just ask yourself if all of your funds would be in those same conservative investments if you had 5x the savings. You'd more than likely be more willing to consider putting a significant portion of it at higher risk, particularly if you have heirs that you would like to pass it on to (which may or may not be a good thing for the heirs).I can't speak for others but I can speak for myself and my wife. When the US economy crashed we did take a hit but fortunately not a really bad hit. As we planned and approached retirement we dropped any investments which may have been considered high risk. Matter of fact my suggestion to our financial adviser was what I called "snail funds" a reference to lower return but much lower risk. I was not interested in risk as we would never be able to put back any loss before we retired and I wanted to retire, not continue to work trying to cover losses. While we are not rich, we are comfortable and I am good with that. Last year we made about 9% and I was ecstatic with that return. The young can likely afford much better to have a larger share of their investments in higher risk funds than us older people.
