How long would potatoes keep for?

This might seem like an odd question but just wondered as we bought some a few weeks ago and I keep forgetting about them!

Just wondered if it was safe to eat them after they had been sat in the cupboard for weeks. they look o.k. on the outside.

If they've been in a dark, cool place they'll probably be fine. If they've started to sprout, rub off any shoots before preparing. If they've gone green, cut out the green bits as these are toxic. If they look wrinkly or they've gone rubbery at all.... chuck.

Thanks, will check them before I use.
