I am 57 year old male. Noticing some changes in my fingernails. Softer than normal more easily ripped, etc. slight varitions in nail bed, small ripples in a couple. I am a construction supervisor but use my hands often in the field. I am otherwise in pretty good health. No meds, no diabetes, no high blood pressure, etc. a little heavy at 204 and 5-10 but getting exercise daily. Any thoughts for me to investigate.
