I have been a long time advocate of blood and organ donation. Ever since I have had a driver's license I have been a registered organ donor. However, it took me a bit longer to donate blood. My first trip to Canadian Blood Services was with JennB in 2010, and I am ever grateful to her for dragging my 25-year-old scared little self to the clinic and kick starting the next 6 years of fairly regular visits.
I don't have time to type up a convincing "you should go donate" post at the moment but you should! Also, there is a new app for your cell phones that makes finding clinics and booking appointments super easy and convenient - I love it! They also have new branded band-aids for afterwards, check out the photo of my arm from my donation last week!
