Think of areas that set pharmacist apart from a physician, dentist, or nurse. Apart from the general helping others and interest in science, what do you think makes being a pharmacist special? Im sure in your personal statements, you have given reasons why you chose pharmacy as a field to go into, maybe from your volunteer experiences at the pharmacy, what not. For me I think a pharmacist gives a personal and friendly aspect to the world of pharmaceutical drugs where there are so much new advancements and knowledge being made. And seeing that the elderly take combinations of pills as part of their routine makes it so important for a professional to educate and help them understand what they are taking and the positive/negative effects of taking these drugs.
Of course this is only a small but major part of population that uses drugs/pharmaceutical products extensively as their primary form of treatments, if not the only ones as many diseases do not have instant cures, such as Parkinson's. Pharmacist roles are expanding and I think it depends on the pharmacist themselves, current and future ones, to find, explore and implement ways that would help them better serve people.
