He must have been quite a man and you obviously inherited some of his intellect.
I know it was hard seeing him failing in his last 5 years and that is sad.
BUT, he had decades of a high functioning life.
Thus, the vast majority of our lives are well worth living.
Actually, he was incredibly physically lazy. Never did a single chore in his entire life. Never threw out the trash, mowed or watered the lawn or washed a single dish. Just loved to read and eat. When he was the Deputy Direction of the State Dept of Labor and was offered a promotion, with much higher pay, to be the Director he turned it down. I remember asking him why and he just said "more work".
Now maybe RP may say it's a fair trade off of work and free time but he had seven kids to support and we weren't living in the lap of luxury. I got a job at 10 yrs old and always had one throughout my teens so I could buy more food. Powdered milk, canned ravioli and tuna which I kept hidden in my closet. I was skinny as fuck and I knew lifting weights wasn't going to do it by itself.
I agree with RP that if you are single and have no dependents then you can opt for more free time over work. But if you decide to have a big ass family then it's less about you and what you personal want.
The only point I was making was that it's so sad to see someone, anyone, just waste away. Either that or you die young which is another tragedy in itself. Mark Twain once remarked that it would better if we started out old and grew young.
I'm a Christian and believe in God but that doesn't mean I don't question things and see and admit that there are some things that obviously don't make sense. I mean, none of here our angels and it is God that is all loving, but if you could create a world for "your children" that you love so much don't you think that you could have done a better job?
That's why I always say that a more interesting question is not whether or not God exist, something like the universe doesn't just appear out of nowhere, but a more interesting question is whether God is good.
