We are a Simulation running on Servers belonging to an Advanced Species

Kinda sad but most likely true...

Medical Technological Development created methods of indefinite "anti-aging" long long ago. Along with this, quantum computer networks were also developed with the capability of simulating every aspect of reality as it is interpreted by the human brain.

They use these quantum computer networks to "screen" humanity. They have created this/these holographic simulation(s) as (a) screening area(s) where they just pick and choose who they allow into the "real" based on certain requirements. Think about it, in a world where physical immortality is possible through medical science and technology, how else could it be?

Those with access to such technology would have some decisions to make. Certain questions would inevitably arise. Would the ones with access to immortality inducing technology be able to intermingle with those who do not? Why would one be denied access? Is everyone respectful of the rights of others? Does everyone deserve indefinitely extended life? Are humans born inherently "good?" Many other concerns with natural balance and overpopulation would also arise. When no one dies, yet reproduction is still possible, overpopulation and resource shortage can happen very quickly.

They created these virtual holo-realities so they can just pick and choose who they share their immortal universe with, and the rest just live out their lives, all the while, they maintain a fragile equilibrium with nature.

Immortality is one of those things that, if everyone knew it was possible, it would do more damage than good. If people knew for a fact that this was the goal, would their actions and convictions be genuine? Its just one of those things that you dont get to know about.... until...... well ...you pass the test.

So does cheese make me constipated because a glitch in the simulation or is lactose intolerance built in to make it more believable? I sure like cheese. Maybe there's hope.

Lol... yup pretty much.
