"How many of you have considered being an organ donor? I never considered it, until I learned my

kidney had failed. The doctor said a kidney transplant was my only option. That or die. This photo shows
what I looked like then, 18 months ago.

Pretty grim. You can see what I look like now, thanks to a new
kidney. Another person's tragedy gave me life and life for four other people, as well. That's why I wanted
to talk to you today about signing an organ donor card. I felt that if you could hear it from someone you
know personally, you could see for yourselves just how important organ donors are to people like me.
And there are 44,000 others still waiting." This speech introduction omits which function?
