The Spanish flu was previously the disease event that caused the biggest loss of life in the United States; the Centers for Disease Control and Prevention estimate that 675,000 Americans died during the 1918 pandemic, in waves of illness that stretched out over roughly two years in this country.

According to STAT’s Covid-19 Tracker, Covid deaths stand at more than 675,400.

Smallholders produce one-third of the #world’s #food, less than half of what many headlines claim

source: https://ourworldindata.org/smallholder-food-production

Most (84%) of the world’s 570 million farms are smallholdings; that is, farms less than two hectares in size. Many smallholder farmers are some of the poorest people in the world. Tragically, and somewhat paradoxically, they are also those who often go hungry.

...

Smallholder farmers produce 29% of the world’s crops, measured in kilocalories. Less than half of previous claims. They do so using around one-quarter (24%) of the world’s agricultural land. They account for a bit more crop production than land use because smaller farms tend to achieve higher yields. This is very labor-intensive work; smaller farms get higher land productivity, but lower labor productivity.These farms account for an even greater share of the world’s food supply – one-third (32%) of it. This is because smaller farms tend to allocate a larger share of their crops towards food, rather than animal feed or biofuels.

Revisiting the Marshmallow Test: A Conceptual Replication Investigating Links Between Early Delay of Gratification and Later Outcomes - Tyler W. Watts, Greg J. Duncan, Haonan Quan, 2018

We replicated and extended Shoda, Mischel, and Peake’s (1990) famous marshmallow study, which showed strong bivariate correlations between a child’s ability to delay gratification just before entering school and both adolescent achievement and socioemotional behaviors. Concentrating on children whose mothers had not completed college, we found that an additional minute waited at age 4 predicted a gain of approximately one tenth of a standard deviation in achievement at age 15. But this bivariate correlation was only half the size of those reported in the original studies and was reduced by two thirds in the presence of controls for family background, early cognitive ability, and the home environment. Most of the variation in adolescent achievement came from being able to wait at least 20 s. Associations between delay time and measures of behavioral outcomes at age 15 were much smaller and rarely statistically significant.
