Research suggests that mentally demanding jobs may protect against Alzheimer's disease by increasing brain cell activity and maintaining cognitive reserve. However, the exact link between job demands and Alzheimer's is not fully understood, and other factors such as socioeconomic status and environmental exposures may also play a role.
Anal cancer rates have increased by 160% in men and 78% in women over the past 30 years, with African-American men showing a particularly sharp increase. Human papillomavirus (HPV) infection is necessary for most cases of anal cancer, but smoking also plays a significant role.
