Chocolate is good for the mood and has a high antioxidant content if it is dark, milk is good for the bones, alcohol in moderation is good for your heart and as a stroke preventative and helps ward off Alzheimer's (read this). This is important to me because now that I have dealt with suicidal tendencies, I am looking at the prospect of living a long life, so prevention of Alzheimer's and remaning functional and independent into my old age is an important long-term concern. All my grandparents lived well into the old age which gives me a high life expectancy. I do not smoke, have low cholesterol and low blood sugar and low blood pressure, do not engage in prolonged sitting (which slashes two years off the life expectancy) -- all of those good things also favor a longer life. My mother did not live a long life - she died of metastatic breast cancer, BUT: 1) I had children early and breastfed for the total of 8 years which lowers my risk of BC 2) I got tested and I am not a carrier of BRCA so I am not high risk for BC 3) If I find a lump, my GP will get an email that very second, while my mom, irrationally, waited with reporting her lump for a YEAR. Early detection = better prognosis. So with my good outlook with respect to breast cancer, Alzheimer's prevention looms large. Heart disease - probably not so important because I have BELOW normal cholesterol; stroke - probably not so important because I have always had low blood pressure and I eat a low sodium diet because I have always liked it; Alzheimer's prevention is very important. Walking helps prevent Alzheimer's, too.
