 Part of the aging process is a loss of eyesight. The amount of sharpening that people over 50 find pleasing may not be the same as for people in their 20s. It is worth considering sharpening to obtain a _plausible_ result (matching your everyday perception) rather than a _pleasing_ result (that may look good only to people with the same eyesight as yours).
 
-Finally, assessing the sharpness of images zoomed to 1:1 (100%) or more is a foolish task. In museums, exhibitions and even on screen, the general audience looks at images as a whole, not with a magnifying glass. Moreover, in most practical uses, photographs rarely exceed a resolution of 3000×2000 pixels (roughly a 300 DPI print at A4/Letter dimensions) which, for 24 Mpx sensors, means downscaling by a factor of 4. When examining a 24 Mpx file at 1:1, you are actually looking at an image that will never exist. Sharpening at pixel level, in this context, is a waste of time and CPU cycles.
