I am 43, I did my MCSE when SQL Server 7 was the mainstream, I have done my best to move with technologies as they have been developed and released and follow best practises, as a result I find my SQL code today is far more efficient because of it, it is far to easy to go through training and then sit back and think I'm done now, I think we need to constantly question how we code and learn from new develops in our field.
