Death
Warning: It is a touchy subject so read with caution.
With science making advances each day the life span of an average person is close to 80. People with a little more money can prolong that to 90. Now if the time came would you choose to die of old age or would you choose to take your life when you were no longer a normal functioning human. I choose the latter because I don't want to be a burden on my children at the time. Sure it sounds senseless but its a lot less painful to see someone wither away than to suddenly wake up and find them gone.
What is everyone else's opinion?
