A death always leaves an impression.
A fingerprint where their presence once was. A footprint where they walked in and out of your life so soon. Whether you were close or far, their memory stays with you.
It's common, when remembering those who have passed, to reflect upon your own mortality. You may be young, you may be old (you can decide which one you are), but it's not the fact that you could die at any moment that occurs to you. It's not that you can be taken away into the curious black.
It's the thought of what you can leave behind for your loved ones. That may be money, land or gifts, but always, you will leave behind love. You will be cherished, you will be remembered and you will be loved. In the end, it doesn't matter how long you live or how soon you die. What matters is how you are remembered by everyone you care about, because it's up to you how you love people.
You can die tomorrow, next week, next year or in the next decade, but the only thing worth living for is your own little portion of humanity.
