People's levels of happiness vary at different points in their life. In a recent note to clients, a Bank of America Merrill Lynch team led by Beijia Ma shared a chart using data from Nielsen, which shows people's self-reported well-being at various ages. The most striking thing from the chart is that people report the lowest levels of well-being in their early 50s. Notably, this is the age that most people are starting to seriously think about their retirement plans, might be figuring how to pay for their kid's college tuition, and even thinking about taking care of their aging parents. However, also interestingly, people report increasing levels of well-being after their early 50s. And, according to this chart, people report the highest levels of well-being in their 80s. Of course, patterns like this can change over time: 30 years from now, today's 50 year olds could end up less happy than today's 80 year old, and today's 20 year olds more happy than today's 50 year olds. But at least for right now, middle age appears to be the low point for self-reported well-being. Here's what the BAML team had to say about well-being and aging: According to Nielsen, there is “scientific evidence that people get happier as they get older. While there are differing theories as to why this is, most agree that it is an acceptance of aging that promotes contentedness. Logically, this acceptance is more apt to happen with older people.” In OECD countries, more than half of 65+ cohort report to be in good health, which means that not only do the elderly have more free time, but they would be equipped to take advantage of it. In any case, check out the full chart below. [Screen Shot 2016 05 16 at 8.15.58 AM]BAML NOW WATCH: FORMER GREEK FINANCE MINISTER: The single largest threat to the global economy
