In the last fifteen years, we've learned a lot about the hormonal influences. At least one of these was discovered accidentally, gherlin, a hormone secreted by the stomach that increases appetite. We learned of the importance of gherlin only by studying people who have had stomach bypass surgery for obesity (bariatric surgery).
When you remove part of the stomach, you decrease gherlin levels, which in turn decreases the desire to eat. Other hormonal influences, such as leptin that has a role in regulating hunger by secretion in relation to its fat supply have also been uncovered.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
