Roman church decorated with 4k skeletons
A great many people are incredibly uncomfortable with the idea of death, and installations like this, and similar works of art, are a great antidote.  Accepting death as the price of life might be a bit difficult for people raised in a culture that worships perpetual youth and which dreams of immortality, perhaps in the form of a digital silicon upload, but it's really a sign of maturity.Taking a minute or so out of every day to meditate upon the inevitablity of your own death is good for one's mental health - and can be motivating.  If there's something you want to do, do it now - tomorrow is not guaranteed!
