I've been reading a lot about Ted Williams recently and having your body frozen for $150K might be the most anti-Mustachian thing ever, even when you won't be using the money anymore.
Our second home/weekly beach vacation rental is a block from the ocean and backs up to a canal leading to a freshwater bay. My instructions, hopefully for 2060 or beyond, is cremation and to have my sons and perhaps grandchildren and great-grandkids divide my ashes into two containers, ride a flotilla of paddleboards out into each body of water and dump me at sea. Then come back to the house, a key part of the FIRE plan, and have a party.
