Yeah that's a tradition called 'the viewing' and my family does it too. Granted, we were never forced to approach the body. My mother outright won't do it.
Embalming can sometimes make them look doll like and unrecognizable. I don't really enjoy the tradition. For some people it's an opportunity to say goodbye. I'd much prefer my last memory of a person to be a living one and not of the corpse.
Oddly enough, I can remember the day my dad was found dead but I seem to have completely blacked out any memory of his funeral.
For the better I suppose.
