My story is similar to yours, except that I am 42 now and got my bachelors degree at 40. I am currently working on my masters degree and will finish in 2010 - at 43. I have been working in the IT industry for about 10 years so that is an advantage, but IMO I am just reaching my prime in the industry, and have plenty of growth ahead (and $$$).
As opposed to many certifications, a college degree LASTS FOREVER, so get one whether you think you are an old man or not. You will be thankful down the road. You will get hired upon completing the degree and after a few years in the field you will have many opportunities. You will be promoted to management faster (if you choose to go that direction) and will grasp concepts quicker than the younger crowd if your mind and passion is truly in the IT field.
The thing you have that no 22 yo graduate has is life experience. You know how people behave in situations from living many years more than the younger crowd. If you have a house, wife, kids, car payments, etc., this shows a level of responsibility that a youngster cannot claim at that point in their life.
As Nike used to say - Just do it! You will have no regrets - until the student loans come due of course...
Why are you linking that stuff here? You think anyone from and IT department that lauds the security of IE6 actually reads Slashdot?
I am from the CO state IT department (not a webdev), and frankly I find this thread hilarious! I only use FF and when this site didn't work the other day (I did not heed the warnings), I used my handy FF add-in, IE Tab.
