Thank you, Also, PSA, check your blood type because if you are O-, not only is your blood type rare(3% of the world's population), you can only accept blood from other O- people

O- isn't even the rarest blood type, B- is only 1% but they can accept blood from more than one blood groups(-B-, O-). So you should think of banking your blood overtime in case of an emergency.

Also Also, O+ is 50% of the worlds population, and can be accepted by many blood groups(A+,B+,AB+,O+), so consider donating blood if you fall in that group(or really, if you aren't, its costs you very little and your body relishs it in less than 2 weeks).

Edit: linked the wrong article. Wanted to like the article that talks about blood group distributions in the world buy couldn't find it.
