Yes as long as both families agree. Humans know right from wrong when they are around 7.
They should also have to get a job and work at 13. Americans are just gonna get fatter and lazier and soon this country will start treating people in their mid 20s like children. We need to get back to the way things used to be. Americans are immature because they have terrible parenting. I started working in my dad's shop when I was 8 years old, graduated high school at 16, had save my first 10k (that I earned myself) before my 18th birthday, graduated college at 19, and paid off my home at 29. I also became sexually active at 13, I knew the consequences of my actions because I was made to take more and more care of myself at an early age. Parents now days want to hold their kids hands until they are 30. It's time for Americans to grow up. I'm not saying it's right to prey on the young, but what parents are doing isn't good either, stop sheltering and start letting them be responsible for their own actions.
