I quit cigarettes on Monday the 18th February, 2008 at 8:30am.
That means that I have been smoke-free for the last 46 weeks, 1 days, 3 hours, 34 minutes, and 40 seconds.

To put it another way, that's: 27,920,080 seconds.
or 465,335 minutes.
or 7,755.58 hours.
or 323.15 days.
or 46.16 weeks.
or 0.89 years.
or, if you're materialistic, €2,406.35.
or 6,463 unsmoked cigarettes.
