Your DNA mostly isn’t yours anyway. Your siblings are largely the same. I did a 23 and me years ago. No regrets yet. I’m eventually going to die probably in 40-50 years. I just don’t see how it can be used against me.
Cats are nice, but dogs are man’s best friend for a reason. Some cats will defend you, but most dogs are ride or die. And they can read you emotionality, just like we can read them.
