I've made some updates to my last blog post:
https://aurav.neocities.org/blog_posts/blood_dono_psa.html

I've added a disclaimer at the start to the effect of "I'm a USian, please research for your own country." And I've added a bit on asinine eligibility requirments (you can't give blood if you're a guy who's had sex with another guy) and how it's fine to say "fuck it, they don't deserve my blood then." I still think you should give if you can, but this and similar """requirements""" are fucking ridiculous.
