From what I remember, 11 years old is stage of concrete operations, and last is stage of formal operations.
The child cannot conserve weight or length, but given so close to then next stage, I am willing to bet your child can. Callaway, what happened before your child got scared of sodium chloride?
I got another question, do you think you could run a mile faster than me, given that I have done an 11 hour aerobics session at almost maxium capacity, and I was 27lbs away from 12%body fat I wanted to be at. I had no food and was going on caffeine low also. Your husband could make a little cash doing nude shit for christ sakes, I got in thee with 24%body fat, but maybe because I exercised so hard, and stopped eating junkfood, it helped me get in to shitty back page. I must have made a mistake in the calculations I fed into the machine when it said 5%. Then all your husband would have to do is raise his arms and darken the image. A midly devolped 6 pack comes out, that needs image darkening. Maybe I was dehydrated so much that it looked good. Fuckn nieve, people. People who don't do well with lifestyle habits can mess up, and if you keep up, you can put one over on them. Quote on quote NT's have paid me to much cash back. Stupid fucks. Overweight people can be healthier than skinny people if they are fit like me. Repeating question, do you think you can run a mile quicker than me?
