I think a death-centric way of thinking about life is unhealthy.

The fact of death isn't what makes things valuable or meaningful.

The fact that our time span to enjoy things is limited also isn't what makes them valuable or meaningful.

The quote is describing much more than mindfulness. It's saying that values and meaning are right in front of us. To reduce that to mindfulness misses the value in what it's saying.
