People also tend to have investment bias. Once you've invested in something, you're likely to think it is more valuable than if you haven't. To put it simply, we humans have trouble thinking from a different perspective, and we tend to focus on what we'd lose rather than gain. Thus, people who own their own business would be biased towards thinking that running their own business is the better option.
Another interesting factoid I read somewhere today: on average only 15% are fit enough to even reach the egg. Yet sperm fitness has been measured to increase after exposure to pornography involving men and women, while this effect is apparently not observed after viewing lesbian pornography. The theory is that seeing the competition somehow makes the sperm more competitive. And that's why it's better to hang around with your fellow HN'ers than your nay-saying friends.
I was not born. born happened first, and the creature existed for a while, and "I" am the emergent sentience.
It wasn't "my" sperm since at that point I wasn't. "I" couldn't have been born anywhere else, at any other time, into any other situation or any other family. It's a nonsense idea.
I've always hated that "statistic". I'd rather look at it this way...
99.9999% of all sperm fail to reach their destination. Yours won. Keep winning.
