Gazza does look terrible, you are right he has aged an awful lot over the last few months, i think his body is finally giving in on him which is not unsurprising given the amount of abuse he has put his body through over the years with the Drugs and especially the booze. I don't think it will be 2 or 3 years until he kicks the bucket though if he is still with us this time next year, i will be amazed. If he doesn't stop drinking which i don't think he will as he is too ill and too far gone then i'd be amazed if he isn't dead by the time he is 50 years of age.
Gazza also has a lot of mental health issues that i think need addressing and putting under control if he is to have any chance of beating the booze but the thing is i don't think he wants to stop drinking and knowone can stop a person drinking long term if they don't want to, so really it doesn't matter if his new girlfriend genuinely loves him or is a Gold digger who is tagging along to get famous, she won't help Gazza in my opinion. Also a 3 day detox and stay under the mental health act won't help Gazza one bit he needs a lot more help than 3 days.
