Can organ donation cards be sent to friends?

If it were me, I would send it. If donating this useless body can give a few unfortunate poor people more hope, then I will definitely be more willing to help others when I am alive, so I will register my body donation. This is my motive. Because it will let others know that I have done something beneficial to others, then I will be happier and more fortunate that someone knows that I have done something good. If the onlookers are very concerned about what happens after death, then he will admire me for two more things; If that person doesn't care about the world after death as much as I do, then he should also understand my thoughts. What a sacred thing this is. I don't think there will be cynicism. If there is, it can be seen as a filter for people in the circle of friends, so that you can see some people more truly. Moreover, after seeing your circle of friends, people who share your thoughts may also have the idea of donating the body. Then, there will be a few unfortunate people in this world, with less pain and more light.
