Philosophy - How do u prefer to die???

But don't u think dying of old age is much difficult coz u suffer much when you die of old age... Its not like u become old and u pass away like....on to off...in one short snap...You've got to suffer and thats what makes it the hard way of dying... what do u think of people who passes away when they are sleeping without any illness or disease??? Do u think they suffer when they die???
