Have you thought about end of life decisions?

I have started to think about end of life decisions lately.
I may only be 60 but so many people die "early".
I have nothing in place at the moment. No will, no care instructions, no plan on what happens if I become incapacitated.
Nothing in place regarding internment.
I am a registered organ donor but who would know that at the time of my death?
I have no one I have confided in about these issues.
I think it is time I talk to my GP to get some advice about these important issues.
