I did it and you should too.

What's a living will?

It is where you declare what you want to happen in case you are in a medical state where you cant make decisions and give that decision making over to a family member or friend. It lets the doctor/family/courts know who is in charge, and you also declare if you want life saving measures if you are terminal, to be kept alive, or not. DNR means "Do not resuscitate". You give a DNR order if you don't want to be kept alive in case of terminal or vegetative state. It also tells people what is to be done with your body when you die.

Living wills not only protect your wishes. It can also prevent fights between family and friends, and even false accusations in court cases. Living wills, even if you don't have tons of assets are very important.

In my living will I declared that I do not want to be kept alive in case of terminal illness or vegetative state. I gave power of attorney to my friend John in case I am in a medical state I cant make medical decisions. I also declared to have my body donated to science when I die.

Pretty much. A will comes into effect after you are dead. A living will comes into effect while you are still alive. In some countries this can be used as a tax dodge.
