I got this. I'm from farm country. Here (in Nebraska) sorghum is called milo.
We don't plant it as much as we used to because soybeans kind of took over, but I still drive past a field now and again. After harvest (small, orange-maroon bb sized seeds) the leaves are thrown into a silo for ensilage. They have a high sugar content and mixed with other grasses and fermented in a silo they make great cattle feed.
Also sorghum molasses. Milo is also found in wild bird seed and it's fun to pop like popcorn because it looks like cute miniature popcorn AND tastes good. It's fine for your rats or any grain-eating animal.
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.
