I was just thinking how you have to sacrifice some blood to perform a summoning jutsu. Usually, ninjas cut their thumb with their teeth to seep out some blood. My question is do they ever get an infection lol? I know that may be a silly question but if they are in a heat of battle, their hands I bet get undoubtedly dirty. So, when they cut open their thumb, can't bacteria sneak inside? But then again, there are medical ninja.
Idk, I just thought about this so it may sound dumb but I just wanted to write it down before I forget about...(which I should have just done lol)
