Actually...I've put a lot of thought into this very question...we're retired, not much to do!
Anyway, I have a very large family...6 sisters, 1 brother and I don't even know how many neices, nephews and great neices and nephews but...
First and foremost...I would find the very best medical care and advancements for Parkinson's patients and do whatever I could for my Dad.
We only owe a little on our house so we would pay that off, buy a waterfront home somewhere warm, get a new motor home and a few new cars.
Our son has some serious back issues so we would make sure he could retire early.
For all of our family members we would buy them a new home, new cars and pay any debts they have. For our younger neices, nephews and grandkids we would start a college fund and put some $$ aside for their future.
We would also pay off everything for our daughter-in-law's Mom. She's the nicest lady ever but circumstances have put her in a position where she will have to work forever...but not if I can help it!
I would make donations to as many non-kill animal shelters that I could and I would start some kind of program to benefit children in foster care.
So, there you have it...my waste some time, pie in the sky, high hopes and dreams...but, somebody's gotta win and it may just be me! Like they say...go big or stay home! Forget the lotto...you got your PowerBall ticket??
