Symbolic Immortality

Most people are trying to live on symbolically by having children. In just a few generations, there might not be any of you left in your children. After 20 generations, it's point zero, zero,zero, zero for you. I have never had one student go, he no, it's really important to me. It's just, it's not. And i've had people get very upset with me when i've brought this up,. But do the malth think about it, 99 % of the people don't care who their great great grandparents are.
