This is convoluted and may take some serious expertise on your part, but I need some ideas!
My MC is exposed to low levels of radiation poisoning, and has been exposed from his teen years, which I know would impact his testosterone levels and therefore his development. How would that have impacted things like his height, weight, behaviors, etc.?
I'm trying to have him look/be as "normal" as possible, so that the reader finds out about the radiation later, but I know that's going to do a number on a body. Any ideas for me to "hide" the radiation symptoms?
