I didn’t realize you were that old. At your age, it might be OK.Correct. In my bank of course, but some amount with me always. Don't forget I am 86.
But for those of us in early retirement, still in our 60s and needing our money (and purchasing power) to last possibly another 30 years, keeping it in cash will cause us to lose out to inflation. Stocks average about 10% - 11% a year, over time, and that’s the way to go - with some guarantees mixed in, such as an annuity and cash.
