I am not sure what the big deal is with these tests. Fore example, My father was from germany. And if I were to go to Germany, and sit in a bar and tell the men there that I am German...they would laugh their asses off. Nothing about me is german. I was raised with jewish american values, language, sense of humor, taste in food.
I have nothing in common with Germans, except for a DNA test.

If there was an opening for a good job for a "German"....I would not apply. That would be hypocritical because I know zero about the german lifestyle, values, sensibilities. I would be a fraud...except for the DNA test.

Thats why I laugh at people who claim to have Indian background and getting jobs at Indian casinos. Some of them are as Native American as I am German.

There are probably multigenerational americans that marry a German spouse, that are more German than I am. They probably know more of the customs and history, and sense of humor of Germans. I know nothing of the sort.

so for adults like me, older in age, what do these tests do for us? Its not like I am going to start to wear a kilt if I find I have 10 percent Irish in me. I wont start eating cornbeef and cabbage, I wont take bagpipe lessons, and I wont all of a sudden like U2.
