Would you want to legalize.....?

As you get older you get more sickly. The old/diseased suffer on a day to day basis and sometimes the medicine or treatment doesn't work.The people who are old and sick enough that they live in pain should have a Choice to die rather than suffer every second till their body gives out.IF you ever had a pet that was put down because they suffered from sickness you will understand me well.I believe that the old and sick should have the option of euthanasia.I would rather see someone i love go peacefully than live the remainder of their life suffering every second.Do you think euthanasia for humans should be legal?
