Affiliate Marketing Secrets

I just recently have come across the profession of PA looking online, after learning about it much more I have determined this job seems very very positive as far as salary, job security, and best of all helping people would be my niche for any career choice. I am 19. I assume I would major in biology or chemistry, then apply for a PA program. However I have seen that medical experience is generally required to be accepted. Being my young age and not having certification to do most all patient related work, how would I begin to accumulate this experience? A local hospital has a volunteer program which I applied for, if I were to do that would that be helpful on an application? I’m looking for any advice, preferably from a recent PA graduate, of course any PA advice is helpful, or a physician who works directly with them. I’m very optimistic this would be a great choice for me, so please feel free to give me any and all information and advice you have.
Thanks to all who help me out.
