Post-biological transhuman, obviously. Diet would be irrelevant, and I would be immortal.

I would like to choose Mbuti people because:

1. They are peaceful.

2. They are egalitarian.

3. They have a way to prevent violence, including domestic violence.

4. They have a great sense of humor and laugh a lot.

5. They solve their problems by talking and playing games.

6. They are people of the forest and they respect their environment.

The only difference that I would make is using AK47 against the government and everybody who tries to take their land.

For many reasons, probably the ancient Hawaiians.
