Swearing is a part of life. You definitely need to know your surroundings in order to stay out of trouble. It may not sound very professional but it happens. Swearing has become more and more acceptable though.
Aches and pains are a part of life. Especially as we get older. Anything can cause them from overexerting yourself at work or home....to just sleeping wrong. Doing something nice for someone else can help.
I suffer from migraines. I don't get them on a regular basis, I get one, maybe 2 a year, however they are pure evil. If you don't suffer from migraines then you are lucky, if you do, then you know my pain.
