What really happens to our muscles as we age if we are chronically active?

These are MRI cross sections of leg muscles. Via this recently published study in the journal Physician and Sports Medicine. See also.

Now start by taking the stairs, getting one train stop earlier. doing at least 20-30 minutes of aerobic exercise every day (that’s not a lot actually, probably 5km only), and eating healthily. That’s the least you can do for your body.

How do neurons create memories?

How do connections between neurons become strengthened, so that the connection is ‘remembered’? Scientists know that if they give an electrical impulse to a pair of neurons, the two will communicate more easily in the future. This process is known as long-term potentiation (LTP). The effect can last for weeks, or even months – long enough to make a memory. LTP is especially obvious in the hippocampus, one of the areas of the brain active in memory.
