Yes.... We gots to keep a Good Attitude about this Horse Pucky...

To explain PSA to ppl, I tell them that it’s RA with a auto immune disease thrown in for shits and giggles.
What can I say, I’m a smartass and I try to keep laughing so I don’t cry

It simply means it is not communicable and does not originate from external means. It is our own body attacking healthy cells.
It's a prefix meaning oneself.
Crazy stuff happening inside us. 😒

Words are Powerful, Trust in the Lord.✞

Yes... thanks for the Post Heidi2, I Hope You're doing alright in this Wonderful Month of October. : - )
