Now this might seem like a totally off the wall post, but fuck it, I'm gonna post it anyways.
In a world full of vaccinated blood that kills people (no shit, here is just one story: https://expose-news.com/2023/01/02/baby-in-usa-dies-after-receiving-blood-transfusion/ ) One thing you can do to save other unvaccinated people going in for procedures is to make sure they are getting your blood instead of tainted blood.
If that isn't enough of a reason to get to the blood bank, let me give you one more reason: In a world of PFAS forever chemicals, microplastics, and contaminated water supplies, your blood gets clogged up with this shit over time. If you give blood, your body has to manufacture new plasma, blood cells, etc. When your body does this, it is creating a more pure supply in your own body than what you started with before you gave blood.
These things are filtered out of your donation before being given to patients. This has been directly observed in scientific studies of firefighters: https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2790905
So. Help your neighbor. Help yourself. As a lapsed Catholic who is slowly coming around again to God I might even mention that there are some teachings that mention "love they neighbor," and that giving your blood so that others might live is about one of the most selfless acts you can do, if the enlightened self interest of getting cleaner blood isn't enough for you.
I leave you with one final thought on faith and self passed on to me from someone who was far smarter than I am:
"Pray as if all depends on God. Work as if all depends on you."
