Actually, money came into existance for the sole reason of being a substitute for gold. The old system was, every part of money represented a part of gold in the countries fortune, so there was the same amount of money as there was gold, meaning if a gold bar was 1000euros (just an example) and they was 9000 gold bars, there would be 9000000euros in the country, nowadays - there is a lot more money there is gold in a country. Also with the gravity theory, we woudn't be able to jump if there was too much gravity, it has two ways - no gravity/too much gravity. Maybe you could change Math to Mathematics, as America do call it Math but others call it Maths, could be pretty confusing for some. I like the way you've made up your own phrases: Positive Cash Flow Negative Cash Flow I found it quite amusing personally. I think you've confused yourself with one part; the profit lane. Profit lane actually means how much you've earnt in your set amount of time, the word your looking for is 'Profit' or merely 'Difference'. Just a few suggestions etc. 7/10
