I'm in my (v!) late 40s. Professional career of over 20 years managing teams and projects in mostly public and charity sector. Thinking of a total career change (if possible at this age). Two things I'm (bizzarly) being drawn to are train driver or social work. Anbody in those careers got any tips? Am I too old? Would you recommend? Minimum time to train? I've seen some fast track options for social workers (I do already have a degree but non related subject). How competitive for posts? (I'm in SE)
