For those no longer practising the religion of their childhood, do you still have some residual habits from that religion?

For example, even though I am now an atheist I still tend to avoid pig meat and seafood. I also struggled for some time to form views on sexuality that are based on critical thinking rather than tradition or a mere lack of understanding. A friend of mine who is a non-religious Muslim always covers her mirror at night, because she was brought up to believe that a mirror shows the dead when the lights are off.

What habits and ideas, if any, do you still have for the sole reason that you were brought up that way? Does it bother you, or are you quite happy to go on in the same way?
