iMac shuts down very fast

[martosprint]

I have a 3 1/2 year old 20 inch iMac and have had no problems with it. I notice the past several months or so when I quit it at night it shuts down within 3-4 seconds. It hasn't always been this way and I am not complaining, but just wondering why it's a fairly recent occurrence. It starts up using the normal amount of time but the shut down is almost instantaneous. Everything is up to date with the latest version. I just wonder why it shuts down so fast. I bypass the 10 second wait when shutting down by holding down the shift and option or maybe it's the shift and command buttons. I don't want to try it right now by shutting it down. Does everybody,s computer shut down this fast or is it just me?
Thanks for a reply 

That's probably normal if you're skipping the wait. Maybe you removed an application that would slow down the shut down or something.
