A smaller brain is also linked to problems in old age, such as dementia. All of the 249 people in the study had blood sugar levels in the normal range. However, those with higher blood sugar levels were more likely to have less brain volume in key areas in the hippocampus (memory) and amygdala (emotion and cognition). Shrinkage in both of these areas is

What Your Walk Says About Your Personality

Two personality traits are most strongly linked to walking quickly. Fast walkers are more likely to be extraverted, conscientious and open to new experiences.
