Looking For A Donor

I saw this in a waiting room at the St. Joseph Outpatient Pavilion.

I think the top part says “Would you be my kidney donor?” in Spanish. He’s looking for a O negative kidney. I wonder how long he has been on dialysis, if at all.

I have a hard time even asking family and friends if they would consider donating. This is asking for random strangers to donate a kidney. I wonder if these efforts are effective.
