Help Running Services in LG-P350


So, I watched a YouTube vid on extending the battery life of your android phone and deleted the "deskclock service" and Calendar Storage from the Running Apps list.
I don't know if it was a good or bad thing, but it doesn't seem to have affected it in any way.
But after thinking things through, I thought it wasn't eating up battery life that much at all since I barely use it anyway.

So is there a way to put them back into the Running Services list?
