I need YOUR help

Mark in 2011

My brother Mark is in a nursing home with Multiple Sclerosis. He has been there for many years and he will be there until he dies. It is very disheartening for me that I can't do more for him. That is where you come in! Mark's birthday is in 2 weeks and I would really like it if he gets FLOODED with birthday cards. Mark will be 60 and it would pick up his spirits for him to get cards from complete strangers from around the country and/or world. If you would like to make someone happy buy a card and just write Happy Birthday (more if you would like to) and address the envelope to:
                    Mark Phillips
                    Whitney Oaks Care Center
                     3529 Walnut Ave
                     Carmichael, CA 95608

Please do this for me, for yourself, for everyone. It will make you feel good. I will take pictures and write about it here. He has one card already, but it would be nice for him to get 60 cards or more.
Mark was so sick we thought he might pass away a few months ago, and he is still hanging on, in fact he is getting stronger. I am sure that if he get many cards his spirits will be raised and he will have motivation to get better. Please help.

UPDATE

 I was at Mark's room today and there was a birthday card from President Obama on the board! I don't know how the White House heard about him, but it was really nice and he was proud of it. THANKS!!
