Someone told me of a hunter who shot a bear that was 1/3 polar bear and 2/3 grizzly bear. I said that was impossible for the bear to have been 1/3 anything and 2/3 anything because the bear has TWO parents. So it can only be 1/2 polar bear and 1/2 grizzly bear.

Even if you go back another generation, the bear has 4 grandparents, not 3, so the proportions of grizzly to polar can only be measured with fractions that have denominators of 4.

I told him that if my father were Native American and my mother were Spanish, that would make me 1/2 Native American and 1/2 Spanish. If only my father's father were Native American and my other 3 grandparents were Spanish, that would make me 1/4 Native American and 3/4 Spanish.

I told him you could never be 1/3 anything because no matter how many generations back you go, you can never get a denominator common with three.

I heard many tricks to loose weight in the past. Tricks that can make you loose like 10 or 15 pounds per week and without doing diet or making so much exercise. Some may say that eating what we use to eat but eating it in small portions and eating oftenly during the day can provoque your metabolism to go faster and so loose weight but I dont know if it's true. The thing is that I need to loose 10 or 15 pounds this week and next week. Can someone help me with this. And of course don't say that it's impossible because it's not. And I know that some people know the secret. So go ahead and explain how to loose weight very fast!!!
