you said it yourself though ron, this theory of intelligent, invisible particles is a nice one, I'd love it to be the case, but I wouldn't dedicate my life to the hope that it's true.
What I do know is that in 150 years, when I'm gone (providing these theories of extra-long lives in the imminent future isn't true), I will hopefully have family who will remember me. I want them to remember me as a good man and that is something I am in control of and so I will live my life to make myself and my loved ones happy and my offspring and theirs proud of me.
