Interesting question...

Let's see: I've been doing my current job for approximately 6 years coding primarily in perl with no prior perl experience. Every project is a learning experience. I put in conservatively 40 hrs a week, minus a few hrs a week screw-off time. Then there are the 3 weeks vacation time each year until last year, when I started getting 4...can't forget about medical/maternity leave...carry the 1...round to the nearest whole number...

10,260hrs...give or take...
