Like some have said here, it varies from person to person.
Let me just say, people don’t look at your hand to see whats different. I worked with a guy for about 6 months many years ago. We hung out at work, drank and went to nightclubs etc. it was about 3 or 4 months in that i finally realised he only had 3 fingers on his hand, i cant even remember which hand it was.
