Career Shift

I was once asked if I want to apply for tech jobs and I politely said no because I felt that my knowledge is no longer up to date. I surely need to know more advanced skills in order to work competitively. Given the fact that I have a computer degree in the Philippines, I still don't think that I will qualify for computer job positions here because I haven't been working in computer for the last 10 years and what I learned is already obsolete at this time. No regrets though, as I have decided that I will no longer pursue a career in computer field. I have decided to shift my interest to a medical field.
