Hey yall, I just came across this forum and find it fascinating. I have always loved the science of physics just because it explains so much, and can be applied in so many applications. I am however almost 40 years old. I didnt do that great in high school or first year of college (wanted to play to much), but now I am kicking myself in the butt for not doing more earlier. I guess my question is, am I to old to get into this field do to the demanding work load it requires. I work for a nuclear pharmacy company that is about to install a cyclotron near our local office, and want to get involved in that aspect of the company. I considered a buisness degree (and still am just due to ease of getting), but something in the back of my head keeps bringing up physics. Can someone help this old man?
