Hehe, I do like to imagine one day that we'll be able to link in with our brains directly into some sort of virtual reality world.

The coolest thing about something like that, to me, is just how many physical limitations we could overcome by decoupling our conscious selves from our physical bodies; even if we must remain inside them in the real world. Sure we could fly around and manifest random objects from nothing and be as "young" as we want and everything... but imagine if we could even tap into the areas of our brains that control our perception of time itself.

Imagine that one day when we were 70 years old and our bodies were frail, we could climb into some machine that put our bodies in suspended or slowed animation, but somehow recalibrated our neural impulses to maintain a normal sense of time.

The closest thing to an afterlife that we could create, maintain, and measure. A hundred years, maybe more, of a carefree and limitless retirement from reality.
