16000 Hours

In a year, we have 365 days.

Counting out the weekends, we get 261 days.

Counting out 20 days of leaves and holidays, we get 241 days.

Considering 9 hrs per day, we have 2169 hrs per year.

Approximating my corporate life to 7.5 years,

I have worked for over 16000 hrs as a Software Engineer.

Does that mean I can never make a mistake in my profession on any given day?

PS: No offense meant to the ill-fated pilot but just an observation. It just seems silly to quote a huge number of professional hours against a person to show his infallibility.
