jobs...

a career expo was held today at mlc, there were many universities that offered several pamphlets that advertise courses that are available... after 1 hour, i have shortlisted the following course as points of interest:
aeronautical
nanotechnology
genetics
medicine
neuroscience

ya... well... i guess its either physics or medicine for me...
haha... so confused, i really want to do aeronatical but what jobs are there that require such study?...
