Exercise

I would agree that kids should exercise every day just for a health thing and for brain development. Especially for kids with ADD or ADHD because taking all those synthetic unnatural chemicals every day some times more then once a day can not be healthy. It makes you dependent on a synthetic drug. But I guess you could compare it to caffeine. Everyday millions of people start their day with a cup of coffee or some type of stimulant. But that is a natural chemical but whose to say if theirs any difference between a synthetic chemical like Adderal or caffeine a natural chemical. My opinion is ingesting anything that is not natural on a daily basis cannot be good for you. Even a natural chemical that doesn't really have a good a use in your body is bad like fat. Sure its not bad if you just eat a little bit but once in a while you start eating it excessively you start getting fat and that increases all sorts of diseases. You would need to do allot of exercise for your body to combat the effects of all that fat. Also just to bring marijuana in the picture. All the negative effects it has on your brain, which is that it  reduces your flexibility in your brain and your short term memory and your cognitive health. It does not kill your brain cells it protects them. All of the effects are completely reversible. So with those negative effects on your brain you would have to do brain exercises to combat the effects it has on your brain. You could do some exercises on luminosity.com or any other thing that will exercise your brain. If you do that then you pretty much get all the good benefits of marijuana. Which is higher blood flow, more of a open mind, plenty of anti-cancer properties (if you smoke cigarettes that works against all the good anti-cancer properties it has). But you can't compare cannabis with fat because the cannabiniods in cannabis work on your endocannabinoid system. It helps clean your body, its like vitamins. It consists of CB1 receptors and CB2 receptors these are found literally every were on your body. Your body already makes its own cannabinoids. There was a drug that some smart researches made, it would block the CB1 receptors in your body thinking that since cannabis works on those receptors that blocking those would make them not hungry. Because as you know you get the munchies from marijuana. But when they did this people got severely depressed and killed them self. So we need cannabis and its cannabindiods to function healthy. Fat, sugar and other toxins that your body really doesn't need, will screw up the endocannabiniod system and that can lead to it not doing its job which is to clean the body.
