Why a baggage claim carousel is a metaphor for life itself.

Here are the points which I think justifies my claim:

1. It goes round and round.
2. You wait in eager anticipation for what is yours.
3. People will elbow you in the ribs to get closer to the carousel.
4. If you are a decent bloke, you will help the elderly, the frail and the infirm pick up theirs'. For your trouble, you might just miss your article as it swooshes past.
5. Someone else might sneak in and grab your bags.
6. Sometimes it looks like everyone else has got theirs' and you are still waiting in line.
7. When yours' finally turns up, it might be scuffed, dented, or just totally wrecked.
