Everyone is different! I am 83 years old and worked full time as an engineering consultant until 5 years ago. I have worked out hard most of my life but had quadruple bypass surgery 18 years ago. Started 44 rounds of radiation and Lupron about 10 months ago. My Lupron side effects were the worst I have heard of and I had to quit after 4 months of shots, but I was able to continue hard exercise workouts and feel that I could have continued my work if necessary. You will probably do fine but do not be afraid to get help from your doctor.
