How old do you have to be to die of old age?
70
It depends on what someone considers old.
You're only as old as you think you are.
I've known 65 year olds who have died of old age, and then there's my dad - who is still walking miles everyday and mowing the neighbor ladies lawns. and he just turned 97 on the 13th of April
itzz just of ur inner soul. if u be happy u wanna live as many years as possible even if u r very old. On the other hand if u r dipressed a lot with all u r problems tht too at the age of 28 - 35 , u will prefer to die as u will be thinking ur self very old , weak and withered (though u r young yet )
