I can think of three reasons to remove the word 'message' from the Good Health log entry text:
1. it is redundant & communicates no useful information - all log entries are messages;
2. it forces the Good Health entry to take two lines, instead of one, on many smartphones;
3. it would make it easier to distinguish the Good Health text from all other log messages, i.e. the good from the bad.
HTH,

P.S. The word 'occurred' in the Main Loop Hang Occurred entry is also redundant - all entries result from events that have occurred.
