It's amazing how quickly flying skills degrade. I've got like 200 hours now, but when I was at about 150 I didn't fly for like a month, then got back up for some pattern work and was completely out of whack -- sensations felt foreign, was anxious about landing.. etc..
I love that at least in the US, you can drop it for a while and just get a new flight review and pick it back up -- it's a lifetime cert. The medical certification on the other hand.... that can ground you.
