So, yeah, commuting can be a gift in disguise. But only if you're "lucky" enough to be able to use public transport. Not to mention the environmental benefits.
The south east of England is notorious for crowded public transport. You're basically looking at several million people hitting it at the same time (and driving is a nightmare so public transport is very busy).
In the worst crush loads I've experienced commuting in Tokyo, I could read a small book only by holding it above my head and looking up... Most days weren't quite that bad, but "can't really move" was common.
[I tried to go in late so my morning commute was often downright pleasant, lazily reading in the morning sun... I also liked commuting because it took me through a range of interesting and popular station areas, and sometimes I'd get off and go shopping or meet someone for dinner or something; I found this much easier (mentally) than making a special trip to do the same after a hard day's work. Now I walk to work and sort of miss my commute...]
If you're lucky! I commuted on public transport for a while in the south east of England and if your face wasn't smashed into someone's armpit for the entire journey, you were doing well (or working unsociable hours) ;-)
