I'm currently planning to apply to graduate school this year, and I've realized that I am kind of lost about what kind of program I should apply to. If I wanted to eventually end up doing longevity research, what would be a good graduate program to enter? Should I go for a degree in Human Genetics? Biomed? Is one field easier to get into than the other, if I know my application won't be as competitive compared to others?
Also, is a PhD necessary for biology-related fields? Is it okay to do a masters first to get a "taste" of the field, so to speak, before seeing if I want to commit to a PhD or maybe even try to apply for medical school?
