From PDSA news, and a bit of trivia:
"EXERCISE INCREASES BRAIN GROWTH FACTORS THAT HELP MAKE NEW BRAIN CELLS
Exercise can help you lose weight, improve body image, and lift depression. Now researchers, building on their work from 1992 that showed people can make new brain cells, learned more about the proteins that regulate the brain-building process. They found that exercise reduced the amount of bone-morphogenetic protein or BMP, a protein that slows the development of new brain cells. Exercise also increased Noggin, another protein, and one that speeds the development of new brain cells."
I'll drink to that!
