Cold comfort collage

I was browsing earlier and was looking at a site containing instructions for making collage.

It's all good, easy-to-comprehend stuff - ideal for using as reference, say, as a basic teaching aid. User-friendly, easy to follow, broken down into logical steps and so on and so forth. It has separate sections - following on from the method - with extra tips, precautions, and other extra bits and bobs.

Things take a surprisingly dark turn when you reach the section giving links to related topics.
The first link is How to make a digital photo collage, and the next three links are along broadly similar lines.

Then we get to the last one:

How to comfort the dying.

Clearly, the art of collage is far more multilayered these days than it ever used to be. Is it a metaphor? The glue being that which binds body and soul as represented by the flat surface juxtaposed against the illusion of depth (just off the top of my head)?

Or has there been a poll or survey, perchance, the result of which states that Dying people find collage more comforting than previously thought?

Or should one cut out a series of shapes and colours to stick down on a piece of board which, when held at a distance of a few feet, is then seen to show a sympathetic message?

I think we should be told.
