I don't know why nobody mentioned this but commuting is not killing you. When you have the feeling it's a waste of time it will kill you. Just like a job that feels like a waste of time will kill you.

Check the comments of people who are commuting by bike or by walking. Commuting that way feels like freeing your mind and exercising. That's why it doesn't feel like a waste of time. Same for the people who are programming or reading a book in the bus or train.

Commuting will not kill you. Wasting time will.
