Haha.. interesting question. I will like to live forever only if the following conditions are met:
- The people who matter to me can also live forever
- I can remain healthy and fit forever as well
To me, it will be more of a curse than a blessing if I can live forever but have to see all the people who matter to me die one after another. There will be no meaning in life if I have no family or friends.
Next, the state of my health is also important. Am I living forever in a bed-ridden state? Or am I fit and healthy? I will only want to be fit and healthy, otherwise there isn't much point in living forever.
