all the obvious aside--house,debts,kids trustfunds,couple nice houses-invest a bit too i'd...
1. donate to No kill shelters--build more!
2. build prisons especially designed to house ppl who are cruel to animals and children
3.donate a chunk to diabetes research so maybe someday ppl with it can live better and without fear
4.donate a huge chunk to abused and neglected children and the elderly
5. and just for kicks and giggles i'd design a lightweight suit built to protect ppl such as Rav who cant seem to ride trikes very well
