The thing is; how do you know what they are saying is actually your past. What I know is that I'm a lot indian, some german, Scottish, etc. I tell everyone that I'm Heinze 57, a little of everything.
A friend of mine said she had a DNA test done on her dog. I asked her, would they notice if you sent in human DNA instead of animal. I guess you'd know if they were fakes.
knowing more about my past isn't going to change my future, I know enough to know a lot of my medical history and have shared that with my grandkids so I really don't care about anything else.
