"I figured that is the best place to do it in a week," he said. "It is very hard to get a kidney and there are not a lot of donors out there, or with O positive (blood type). I am universal, but I have to get an O back."
Leibowitz said he was shocked at the amount of people trying to help him out.
"The response has been absolutely amazing. I get very emotional about it," he said. "Over a million people have seen it already and the calls keep coming in in terms of text and phone calls from all over the country, which is amazing."
According to the National Kidney Foundation, 123,000 Americans are on a waiting list to receive an organ transplant and more than 101,000 need a kidney.
The foundation said 17,000 people receive one each year and that 12 people a day die waiting for a kidney.
You can visit the Donate Life America website to join your state's online registry for donation. You can also declare your intentions on your driver's license.
The National Kidney Foundations says letting your family or other loved one's know about your decision is vitally important. Family members are often asked to give consent for a loved one's donation.
You can also consider being a living kidney donor. Living donation is when when a living person donates an organ or part of an organ to someone in need of a transplant. The donor is most often a close family member, such as a parent, child, brother or sister. A donor can also be a more distant family member, spouse, friend or co-worker.
