OK... I'm going to look at the positives / be incredibly crass here and say that there are a few upsides to feeling like you have "someone else's hand" (let your mind wander if needs be). Unfortunately playing guitar isn't one of them. 

Speaking to The New York Times five months after the bike accident which left him with a string of eye-wincing injuries, Bono said:

"I really used to think that my head was harder than any surface it came in contact with, and I don’t anymore. I didn’t come off a Harley-Davidson. I came off a push bike and smashed myself to bits. There is no glory here. 

Discussing his litany of injuries a couple of months ago, the 54-year-old said: It feels like I have somebody else’s hand. I can’t bend these, and this... But they say that nerves heal about a millimetre a week, so in about 13 months I should know if it’s coming back... It’s all numb here [on my forearm], and this is titanium."

While he's still unable to play guitar, perhaps Edge will let Bono lead Numb should they choose to perform it in Vancouver when their new tour kicks off next month.
