Time is something made up by human beings, all relative.
I think living forever would be fantastic as long as one is in good health.
For all I know we already live forever as there is nothing suggesting that our consciousness stops after our physical body decides to throw the white flag.

If you follow Buddism this is exactly what they believe in, we are stuck in our conscious being and come back in different life forms depending on how you behave, thus being stuck on earth forever until you reach nirvana.

So yes we could already be living forever.... so don't be surprised that when u die things might not end. 😜
