Nah i'm just busy in high school with sports and homework and i just ond't have time for a part-time job so i'm just gonna donate plasma for some extra cash... and actually donating blood and donating plasma are essentially the same thing...donating plasma is when they extract the blood from your veins and then separate the plasma which is in your blood and then return the blood back into your system...essentially the same except you get the blood pumped back in you.
