Something to fill in the gap

I haven't blogged in a while. and I don't really have anything to moan about :)

So, here's a philosophical (that's debatable, maybe 'stupid' would be a more appropriate word) thought for you:

Fish don't have eyelids.

So how do we know that fish are awake, when really their whole lives could be one endless sleep walk/swim...?

P.S Happy February :)
