How Tissue Regenerates
The cells of our body have the ability to regenerate our body tissue to accustom our growth, heal from injuries, accommodate our needs, and more. For example, we replace our skin tissue completely in 7 days, and cuts will go away in a week or two. We can almost always heal ourselves perfectly, given enough time and resources. We do require resources such as nutrients and food to heal these cells, but it still takes time, even if we already have the resources needed to regenerate cells.
Quick Regeneration
When it comes to regeneration, some people might think about something like Doctor Who, or regenerating your whole body at once. This however, is not the case with humans. But what if it could be? What if we could create a device that could reinvent the way we heal ourselves? We would be able to heal some of the most gruesome injuries with a moment's notice. If we could perfect a device such as this, then we could exceed the limits of our body. We could live forever.
Immortality
Humans usually die when their cells can no longer heal damaged parts of our bodies, resulting in our organs failing and our bodies dying. But if we could perfect a device to regenerate tissue, then we could restore our bodies whenever our bodies would fail to do it for us, and give our bodies the ability to restore our tissue again once our bodies lost that ability. We could live forever.
