i have to post this again because I posted the first question incorrectly.

 

I know one person that spit in one persons food a lot when he was a child and now he looks like him. they spent a lot of time close. can you explain this? thank you

There is no mechanism where that is possible.

They are siblings?

Most people look pretty similar; two arms, two legs, one head..

I am unsure as to what just happened... regardless, i think this needs to be tested!! Any volunteers. Dibs on being the producer of said spit!!

They're the same person. 

 

 

But seriously, as mentioned by others, there is no mechanism or process by which saliva can alter outward appearance, other than making you look less intelligent when you drool.

I've been keeping this under wraps, but it's called  'Enyzmatic metamorphosis by proxy'.

So when you spit in people's faces, you're just trying to make them look younger?!
