I am healthy and likely to live a long, long time, but I need to make provision for what happens next. So, I grabbed a simple will, added a few clauses, and signed it in the presences of a neighbor couple who very agreeably signed as witnesses. Now if I pass on, the people I care for ... and who care for me ... will be taken care of to the extent of my ability.
It's not vast wealth, but I feel good having made a Will, storing the original with my important papers and sending a copy to someone who will take care of it. I recommend this to everyone, if only for the peace of mind!
