Researchers observed the primates switching social groups and passing information on where to find the ripest fruit
Spider monkeys share tips about where to find food by changing their social groups in a “clever system for sharing insider knowledge”, research has shown.

Why do some people age better than others? Five extraordinary individuals – who scientists are studying – share their tips
Lajuana Weathers is determined to be the healthiest version of herself. She starts each day with a celery juice, is always trying to increase her step count, and meditates daily. Weathers is also 89 years old. And she has no plans to slow down. “I wake up in the morning and feel blessed that I have another chance at a day of life,” says the grandmother of six, and great‑grandmother of six more, who lives in Illinois in an independent living facility for seniors. “I look at my life as a holistic entity, and in that life is my physical, social, emotional and spiritual wellbeing.

To qualify for the study, you have to be over 80 years old and have memory performance that’s at least as good as the average 50- to 60-year-old. There are about 400 superagers enrolled across North America.
