What does end of the tunnel look like in IT Career

After reading so many blogs & discussions from so many industry experts who have been in the industry for so long I always wonder what it looks like in end of IT Career. I am a net/system admin with just over 5 years in industry and when I think long term it?s scary. This could be also because I don?t have second degree to fall back on if IT becomes over populated. Is any one in the industry with more than one degree and have used it both together to work their way up or get more clients since they understand other side and can implement IT side for them. Any way just wondering about other users experience who may be nearing to retirement and wouldn?t mind sharing their thoughts.
