But the most important aspect for us I think is what do the cells need for optimum healing? What kind of fuel do our cells need? It's the most important question of all really and has not been addressed properly by our medical world.
P.s. I think we should rename our white blood cells to "Terminator T1000" cells btw. Because they are quite similar and our white blood cells are probably more advanced.
Our Terminator T1000 white blood cells can electronically scan if something is a part of our body or not and upgrade by transferring memory.

Naming the WBCs as T1000 is kind of futuristic, I'm pretty sure the early scientist would consider the name if they knew about the T1000 hahaha.
