Here's my analyses of DSOTM:
"Breathe" The man (example of anybody) works himself too hard.
"On the Run" Paranoia sets in.
"Time" The man can't accept the concept of time, and he always seems to be short of it or have too much of it.
"Great Gig in the Sky" Fear of death.
"Breathe Reprise" The man isolates himself.
"Money" Either he excesses himself, or he sets his sights on money.
"Us and Them" War is a perfect metaphor for his paranoia.
"Any Color You Like" ..........I don't know.
"Brain Damage" Hospitalization and, sadly, lobotomy.
"Eclipse" Self-explanatory
