I think viewing the body is ridiculous. I don't want anyone gawking at me after I'm dead. After all, what good is a funeral anyway?
Most families choose to have a viewing because it helps them to come to the reality that their loved one is truly gone. If you do not have an opportunity to view, you can fool yourself into thinking the person has not died. Of course, this is an option for each family because you can certainly have visitation and a funeral without a viewing. Remember though, people are gawking because they were friends of the person who has died – not curiosity seekers.
