Hi, I guess this is good idea if you have time.
I'm 34 years old and I started Information Security Degree last year. I was Math teacher since 1996 and now, I want change to IT. Next year I'll finish my course and then I'll start Networking Specialization (lato sensu more 1.5 year), so I'll can became a Professor to teach OS, Networking, OS Servers and shell scripting in FATEC and Unicamp (2 big Universities in Brazil).
Of course, I need to study a lot because I know just a bit of computers.
And I have a website with my resume and my job.
