Am I the only one who feels this market is so supercharged and the geopolitical situation is so unusual that it is time to get out?

Home with an injury and watching TV and switching between business and news. The stocks are so overheated, and there are so many risks both nationally and internationally that I keep being tempted to get out. Yes, I know about “catch a falling knife“ and “impossible to time the market“ but I am 75 years old and very nervous! TIA!
