I use to gauge it to never moving further than a days drive from family which worked for awhile. Later it didn’t matter...but now I’m just 45 minutes from them...on purpose.
The best investment in chaos is family and friends. Money in the bank is worthless.
Real physical money is priceless.
As said I can move quickly if need be in dire straits. Family has wanted me to move closer for several years ...with two sons they’d assist in the move it comes to that. I prefer the distance we have now...Visits are very meaningful and we all have our own life to live otherwise. I chose to give my family ‘space’ to live theirs and I have never regretted it.
