I feel pretty awkward asking this here, but I feel like this is where I would get the most accurate answers. I'm planning to do physics research in academia in the future, and, basically, I have permanent physical indicators that suggest I haven't always been emotionally stable. They're visible in some situations (ex. typing while doing computational work with a research adviser), and I can't hide them all the time. By how they appear, they could be anywhere from only a couple months to years old. I may just be excessively concerned, but do you think people's impressions of me as a result might harm me in the future? Should I do whatever I can to hide them (which might mean wearing clothing that is completely inappropriate for warm weather), etc.? Or does no one care as long as I'm doing my job well?
