Sexual Activity is Associated with Changes in Inflammatory Biomarkers. In older adults (average age ~66), research shows more frequent sexual activity relates to lower levels of inflammation biomarkers such as C‑reactive protein (CRP) and fibrinogen.
The brain of adult men is approximately 10% larger than that of women. Because men are typically taller and have more muscle mass than women, their brains require more neurons to control the body.
Your gut is sometimes called the “second brain”. The gut has 100–500 million neurons, forming the enteric nervous system that controls digestion independently of the brain.
