Bonobos have a male philopatric society; males remain with their birth group whereas females migrate to other groups during adolescence. Sexual activity plays a large role in bonobo society; it is used for pleasure, social bonding, and conflict resolution.
A Letrozole side effect - excessive stomach gas. I have been taking letrozole for a year, following chemo and radio for breast cancer. I suffer from excessive stomach gas. The emissions are so smelly that it is embarassing to go out sometimes.
Your stomach pain could be a sign of stomach irritation from taking advil (ibuprofen). Loss of appetite could be partly from gastritis, stress, anxiety, depression, thyroid condition etc. Take care! http://www.m.webmd.com/a-to-z-guides/digestive-diseases-gastritis. http://www.healthline.com/health/appetite-decreased.
