We are not supposed to know all the answers to all the questions of life. Otherwise our existence would be rotten. Life makes sense through the hope we nurture every day, through this quest for the unknown. And not knowing the date of our death nourished every day in us a desire to move forward and to hope.
For me, no I would not want to know and this ignorance, far from delaying, allows me to add a more to my happiness and that of humanity.
Thats why its so important to live with hope because you never know when death calls.
