I've been cycling to work for more than a decade in a more bike friendly city than LA (presumably), but still a city. What worries me a bit is the impact on my lungs. A doctor friend once told me they could easily tell the country person from the city dweller from looking at their lungs.

Apart from that it is a net positive for me and I wouldn't stop. You have to die one death they say and if it is lung cancer or COPD for me, so be it.
