RLJ (Red Light Jumping). (The definitive bikeradar thread)

if i save 2 minutes a day for my whole life and reach 100, that nets me an extra 50.69 days of actual living time. i feel its actually more stupid to not do it. and just from my own perspective I look at those that don't as being a bit thick.

That'd only work if you bank that 2mins each day and adjust your schedule to make use of it in the future. Assuming a 30 day month and a normal working pattern (m-f 9-5), you'll be getting to work at 5am in 4 months time, at 1am in 8 months time.
