Many years ago, while commuting in college ruined and entire drivetrain in one winter. Instead of cleaning the chain at regular intervals, just put more Phil Oil on it. By the time spring came around the chain was stretched, and both the freewheel and front rings had distinct hooks in 'em.
Have broken one chain, a SRAM. While climbing a hill in winter. Never did figure out the underlying cause. About three links away from the master link. Like William was originally taught to replace every 2,000 miles (less in winter). As these things go, since I've been back into riding have gotten more and more lax about that. Do carry a chain tool in all my bike bags, though. Like the fiber spoke, it's more there for "protection".
