Now i've only been a fan about 3 years (even though my obsession with anything Beatles/McCartney related makes it seem like an eternity!) but even since then Paul's voice has noticeably become rougher and more unreliable (particularly on TV). I'm not just talking about his singing voice either, his speaking voice is even rougher! However he has also aged quite a lot, particularly since the late 90's although that's understandable after losing your partner for many years and of course the second marriage must have caused stress.
Don't you ever just wish Paul (and Ringo) could stay young forever? I know it's selfish and they are both in their 70's but it just seems depressing to live in a world without any Beatles, particularly the guy who's responsible for my favorite music. I realise they could both live another 15-20 years but i'm only 18 and most of my favourite music artists (Bob Dylan, The Beach Boys/Brian Wilson, The Who, Pink Floyd, The Rolling Stones etc) are already quite old and very selfishly i'd like them to live on for years and years.
