This is a very good question and I always contemplate about this.
Personally, I am not afraid of death, as this is a perfectly normal part of human life. Although, I admit that I am saddened by the thought of no longer being part of the birthdays, the anniversaries, the late night conversations, and the bumming out.
To be honest, I faced with the dilemma of living or not living longer than my loved ones. Could I bear watching them die or leave them in sadness?
In any case, I do not want to live long enough, that I will just be a liability to anyone. I want to live life to the fullest while I have the time and energy.
