I applaud your desire to help others, but, without exaggerating, your solution is utterly unfit for deployment.
Each iteration of that loop will consume approximately 5 seconds, most of it sleeping while files that will never be detected are created.
If things that do not need to be in the loop are extracted, the situation improves significantly:
Code:
watchdir=/var/tmp
newfile=$watchdir/.newer
touch $newfile
while [ 1 ];
do
find $watchdir -newer $newfile;
-->FILES CREATED DURING THIS WINDOW ARE LOST<--
touch -a -m $newfile;
sleep 5;
done
There is still a race condition between find and touch, but at least now it's only a tiny fraction of each iteration's wall clock run time.
This is much better, and perhaps it's sufficient for personal use, but if a file cannot go unreported, it's still inadequate.

cp
CP(1) General Commands Manual CP(1)NAME
cp, cpdir - file copy
SYNOPSIS
cp [-pifsmrRvx] file1 file2
cp [-pifsrRvx] file ... directory
cpdir [-ifvx] file1 file2
OPTIONS -p Preserve full mode, uid, gid and times
-i Ask before removing existing file
-f Forced remove existing file
-s Make similar, copy some attributes
-m Merge trees, disable the into-a-directory trick
-r Copy directory trees with link structure, etc. intact
-R Copy directory trees and treat special files as ordinary
-v Display what cp is doing
-x Do not cross device boundaries
EXAMPLES
cp oldfile newfile # Copy oldfile to newfile
cp -R dir1 dir2 # Copy a directory tree
DESCRIPTION
Cp copies one file to another, or copies one or more files to a directory. Special files are normally opened and read, unless -r is used.
-r also copies the link structure, something -R doesn't care about. The -s option differs from -p that it only copies the times if the
target file already exists. A normal copy only copies the mode of the file, with the file creation mask applied. Set-uid bits are cleared
if the owner cannot be set. (The -s flag does not patronize you by clearing bits. Alas -s and -r are nonstandard.)
Cpdir is a convenient synonym for cp -psmr to make a precise copy of a directory tree.
