Aww thank you. I could have written about it forever - as with so much to do with humanity, there's so many roads but I have so much more writing I figured I'd try and encourage people to do their own research and share.
I'm pleased you followed along.
My next one is probably a small bit but I have decided it's best to write about what fascinates me, then I enjoy it if nothing else :)

It's still physiology but yeah - watch for it :)
Love your writing BTW hence the inclusion so others can see too x
