Well, angling them down a bit is what you're supposed to do, so your wrists stay at a neutral angle.

This reminds me of something I see a lot of, but only on pictures of bikes owned by Americans. I see the handlebars angled so the ends point streight up in the air like this:



What's that about? It looks incredibly uncomfortable, you must have to hold your elbows up at a weird angle. Or maybe you're supposed to lean your torso far forward and hold the grips from underneath, like you're doing pull-ups? I can't for the life of me work it out.
