Well, that is definitely a difference; I am 51. I am still in for the long term, although the long term has shortened since I started (or, investing was started for me), in 1958. :)
When you get to be 68, remember me. Calculate how long your mother, grandmother and aunts survived and see how much you will need to live on for your expected life span. My wife will 67, and her mother and grandmother lived to just under 90 without the good health and medical care my wife has. She needs to calculate surviving to at least 90.
There is no room/time to recover from a heavy downturn in political uncertainity at our age. We have friends at our age and older, who lost 40% or more during the Clintoon bubble breaking. They have downsized their homes and lifestyles to try and stay afloat.
I just got off Fidility, selling our Fido Ira's remaining mutual funds and buying CDs or leaving money in the money markets.
Each transaction was slower than cold molasses being poured on a cold morning. So a lot of people are either buying or selling.
There was one 90 day CD paying monthly at 5.1 %. I loaded up on that.
