I have had so many fantasies about doing this but unfortunately I am a year too young to legally be allowed to donate blood and I'm too much of a pussy to diy it past just my regular sh methods. I'm also about a kg or so shy of the minimum weight for donating but I could easily fake that small amount haha
Also, as someone who works for the Red Cross for blood collection, I can 100% tell you DON'T FAKE YOUR WEIGHT. I and coworkers have seen:
-people have a seizure
-people faint and chip a tooth
-people faint and smash their head on a table, requiring stitches
-people faint and smash their head on the pavement
-people projectile vomit all over themselves
-people defecate themselves
-people experience a variety of these symptoms for an hour and a half (happened a few days ago to an older lady)
-people having a heart attack (dude lied about his heart conditions and meds, literally had no pulse when he went down)
and this happens WAAAAAY more frequent when you're underweight, first time donor, barely at donor age, and don't hydrate or eat properly (stupidly happens a LOT in high school blood drives; a red bull is NOT hydration, and a bowl of cereal 4 hours ago is NOT breakfast). It's red cross policy that we can't force a weigh in for whole blood donations, but do know that there are reasons why we have height and weight and age requirements. We're not about stealing someone's life to grant a life.
