You would be immortal and all basic amenities essential for physical survival would be provided. You can have the age of your body according to your choosing and your mind won’t blow off by accomodating endless amount of memory.
You can choose anything you desire and that too at any instant which may or may not exist in real life, like an endless supply of something or a companion with the same immortality powers as yours, but you won’t be able to change it in the future and there would be no going back. Also you cannot alter your mind in any way that would enable to let you tolerate living for eternity or not get bored of things.
Ideally you would want to have everything just to be sure but by asking you the minimum requirements, it would making it more interesting to know what you think you could do without or what matters to you the most.
What is there if not the journey. I still choose life.
Even after being partially disabled for a decade and in near total isolation presently, I still choose life now, as I would then. Boredom is a lack of creativity. Perhaps the entire universe becomes the slow moving simulation of my mind for the Postbaryon.
You eat the same repetitive foods in a cycle just beyond conscious awareness, and yet you do not tire of eating. I can dance to life forever, despite the rhythmic procession, or effrons quale.
