    It is well established that some people are genetically predisposed to a shorter lifespan. It is also well known that lifestyle factors, specifically smoking, alcohol consumption, diet and physical activity, can have an impact on longevity. However, until now there has been no investigation to understand the extent to which a healthy lifestyle may counterbalance genetics.

    Findings from several long-term studies suggest a healthy lifestyle could offset effects of life-shortening genes by 62% and add as much as five years to your life. The results were published in the journal BMJ Evidence-Based Medicine. “This study elucidates the pivotal role of a healthy lifestyle in mitigating the impact of genetic factors on lifespan reduction,” the researchers concluded.

    If you’re a chocoholic you may have noticed that your habit has lately become more expensive. The price of cocoa began creeping up in the second half of 2022. Since then it has doubled, reaching an all-time high in January 2024. That steep rise spells trouble for the chocolate business and sweet-toothed consumers alike.

    Climate patterns are partly to blame for rising costs. Cocoa is mostly produced by small farmers in West Africa. Ghana and Ivory Coast grow about 60% of the world’s crop. Last season, in 2023, the El Niño weather pattern led to unseasonably high temperatures and rainfall that ravaged crops. Total rainfall in Ivory Coast’s cocoa-growing areas in 2023 was the highest in 20 years, according to Gro Intelligence, a data firm.

    This year El Niño has brought severe drought to the cocoa farms, reducing production further. ING, a bank, estimates that this year the gap between global production and consumption will be at its widest since at least 2014. Extreme weather patterns have hit other commodities, too. Droughts in Thailand and India are affecting rice plantations. Torrential rain in Brazil, the world’s biggest sugar exporter, has affected its exports. Besides, other price pressures are specific to the cocoa industry. Swollen-shoot virus and black-pod disease — killers of cocoa trees — spread across Ghana and Ivory Coast during heavy rainfall last year. Tropical Research Services, a research company, estimates that by the end of 2023 the swollen-shoot virus had infected around 20% of Ivory Coast’s cocoa trees.

    Most don’t work anymore, but Americans age 70 and older have seen their share of collective wealth surge during the pandemic. As a group, they have accumulated more than $14 trillion in additional net worth since the end 2019, based on Federal Reserve data. Their share of the country’s wealth has jumped to a record 30%, even though they account for 11% of the population.

    The aging population helps explain some of the gains: there are about 2.3 million more people over 70 in the country than in 2019. But one major driver was the surge in home values and stocks during the pandemic, which benefited older generations most likely to own a house — or two — and hold equities or mutual funds.

    Although people who are over 70 are typically retired, a rising portion of that age group is still working. The share of adults age 65 and more in the labor force reached a historic low of 10% in the mid-1980s but has since almost doubled, even after many retired early at the onset of the covid-19 health crisis.

    Older Americans also have been the beneficiaries of good timing with the stock market, despite recessions along the way. Since 2019, those age 70 and older have collectively gained about $5 trillion in equity gains. Close to 38% of the nation’s corporate equities and mutual fund shares were held by people in that age group, the highest share on record in data going back to 1989.
