LOGARITHMS!! Your heart rate just spiked, didn't it? DON'T WORRY! No, seriously; stress is the opposite of health.
I'm a neuroscientist/artist, former childhood dancer/gymnast/actress. In high school I was a mathaphobe (afraid of math... though I hated it). I always liked science but never "thought I was good at it" and certainly never dreamed of pursuing it in any way, shape or form.
Speaking of shape and form, that is the very essence of biological science: function follows form!
