7. Gnarly nails
Our fingernails can tell us a whole lot about the state of our health. If your nails have spots, strange ridges, discoloration, or are seemingly falling apart, you probably have some serious issues to deal with. Take a look at your nails, and go to a doctor with anything that stands out as strange. Weirdness among our nails can indicate much more serious health issues that need to be addressed.
8. Your physical shape
If you want to live well into your 60s, 70s, or beyond, you need to take your physical condition seriously. That means having a BMI within the recommended range — or, not being overweight or obese. Obesity can absolutely ravage your body, and many of the most common causes of death (including cancer and heart disease) are closely linked to excess poundage. Are you out of shape? Consider it a sign that you won’t last long into your golden years.
