Atoms never touch each other because of electons

[Hepic]

Recenty I learned that there is not real touch. That atoms never touch each other because of electons. I have two question to this.

1) Why we feel the pain(I think is because of brain analysys but I am not sure)
2) Why if I press hard my hand,I will mark that?? Why this sign in my hand will be exists(I will get out the electrons from there?)

Thank you!

1-If you have no nerve connections there,you won't feel any pain.So that's only a problem with our brain.How are you marking?By paint or just pressing hard?
