blood donation

something nice to do for humanity, especially if you have a less common blood type, or a rare one. go figure out your full blood type (what's your rh, do you know?), and donate. make it a cool bonding activity that you do with your friends, family, significant other(s), teammates or co-workers, for the good of others...then go brag about it online to make it even more popular, but also to feel better about your selflessness, get those virtual applause and boost your level in the merciless world of online presence. this can also be a motivator to keep yourself healthier (read it how you see fit, focus on what matters). would you want someone to get bad blood? obviously not! do regular blood check-ups. also, check before you donate if you can. sometimes you might not be the best person to do so, for example, if you have low blood pressure, just got a tattoo or other skin procedures (wait 6 months), smoke pot sometimes (get clean first, you have bigger issues, you are making your brain mush), take diet pills or other medication that you should not, etc.
