Yawn and iodine cure peoples.

Against insomnia as to ventilate lungs, as breathe exercises doing, as deeply breathe in, and strong breathe out.
A breathe with mouth, not a nose, as a few times till yawning, after eyes raise to top, and keeping this pose for 30 minutes,and good night!

And in skin damages a saver is iodine, as grease an iodine of damages,as till long time if damage is strong.
Yes I agree I apply iodine on my swollen finger,after nail cut.
