I think that a lot of people take health for granted in their younger years. I am glad that my health is still more or less not bad. I think I inherited weak eyes from my dad (and I am sure that reading books and being in front of the screens didn't help either.) Both me and my mother have some mental issues. But we can move and are not in pain. I am really glad that my teeth are still good. The last time I went to teeth doctor was a while ago. That is nice because fixing teeth is expensive and I already spent a lot for new glasses.
Health is a very important part of life and focusing in maintaining it, whilst difficult and costly sometimes, is often the best way forward.
