I am middle aged. Just keep your bodies as healthy as you can. I take supplements to help me be as strong and keep my immune system as healthy as I can. A good doctor can help you with supplements and you can support your body. Blood tests can help tell you what you need. Vit. D, B12, etc. Very important to really care for your body. Stay postitive, I have had CFS for 19 years, POTS for about two. I have had other problems. Sometimes we get a hard road,like many people, but we can handle it, we are strong.
