Should high schools require two years or four years of physical education?

Everyone these days are always fusing on how kids are obiece. Well if they think that then i think that they should go to the board and agree on everyone having physical education. These parents these days don't agree on anything that the board trys to do. So I say that everyone has to have at least two years of physical education. Now parents are also fusing about how they have a diet at all these schools, I don't think that is right. If kids wants to be obiece then let them but when kids come to teachers for help about everyone making fun of them then the teachers can only say go to the board. That's just my opinion.
