See, staring at the Sun is another one. Can you actually do it? I've tried it but it hurts quite a bit so I tend to only get a couple of seconds in before I have to fold in the Iain vs The Sun staring contest.

Not for long, the sun always beats me as well. I think half of it is knowing the sun is prepared to stare until i'm blind though.

Nah, it's probably just the pain of feeling your retina detaching.

ah but is it really you're retina detaching or is it that getting superpowers hurts like buggery?

It depends how you get your superpowers.

Cue the Invisible Man joke.
