Why do people who kill cattle have a short life span?

Maybe it's superstition, but there is no evidence to prove it is true. I heard grandma say that killing cattle should be punished. This is what Buddhism says. I don't believe it. It's hard to say whether it's true. In ancient times, someone killed a cow and was killed by lightning. Some people went to hell, were eaten by cows and so on. Don't believe it. This is a rumor. No one can prove it. I hope you are not superstitious. Nobody kills cows now! I'm not talking about killing cows to shorten life when I'm on TV. Don't worry! May everyone be healthy forever! Stay away from superstition? I've been playing computer for so long that I forgot my words! 555555
