If we think all the time that we gonna die any moment, then we will be doing our best in anything that we do.
If this is all the mindset of all people then, all will be doing their very best as much as possible all for good because we're thinking that any moment we will die.
Based on my faith, knowledge and experience, we are born for heaven, and death is the gateway.
If we fear death, then we are going in the wrong direction.
