501's are the original fit. The design hasn't changed since first being produced and are known as an anti-fit. I.e.
It doesn't have the bit of extra material at the seat, it is straight so the material cuts into your backside. This fit only suits people up to a 32 inch waist as it isn't generous to the heavy thighed person.501 are a red tab jean which corresponds to the material type. 618 are an orange tab loose fit jean which are no longer made.
These are very good for a bigger type person, these fit I used to prefer myself. More.
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.
