I now feel slightly less guilty about my growing dependency on AC.

(Is there anything NOK to switch on/off frequently? No evidence.)

• Dependency on AC is very common, so commercial support is widespread.
• Dependency on car is ditto, but the commercial support is pricier.
• Dependency on wireless connectivity is very common, but you depend on other people most of the time.
• Dependency on wpress is uncommon
• Dependency on NY/NJ subway is common during peak hours only. Extra dependency on it is uncommon.
