<p>I just wanted your guys' feedback :D! I'm only a junior in high school, but I've been really stressing over this. Would you guys like to shed some light as to which of these fields would be a better choice? I'm not necessarily looking for a sinecure--just hoping to do something I'll love forever. I would like to go to grad school, but you never know :P...</p>
<p>The choice of major is a really personal one. You have plenty of time to figure this out. You can start college as undecided, take Calculus and the introductory courses in physics and biology and then decide. Astrophysics can be moved into easily from a physics background and there is a whole field called biophysics which can be entered easily from a B.S. in physics.</p>
<p>My oldest son started in physics and switched to biology in his Junior year of college. He is now a Ph.D. candidate in biology but is still using his physics training in his study of biomechanics.</p>
<p>Don’t sweat it for the moment, at some point you will figure out what you like best.</p>
<p>If, in your first year, you like math and (calculus-based) physics courses better, then you will probably like physics better. If you like biology and chemistry better, then you will probably like biology better.</p>
<p>Note that the job market in the sciences is not great. Many science graduates at the bachelor’s and doctoral level end up in jobs outside of their science fields. Physics majors do seem to have better alternate job prospects than biology majors, though, since they seem to be more hire-able in computers, finance, and some types of engineering.</p>
