is battle royale in both humans and animals, even for plants too. Why? Because
the ecosystem changes, the weather changes, the food chain is a combat to chase.

In sickle cell crisis, the abnormal RBC clump together (easily, because of their shape) then obstruct small blood vessels in the extremities and other organs, causing severe pain.
