The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Skin has three layers: 1  The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. 2  The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. 3  The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The honeymoon period tends to last anywhere between 6 months and a year. The relationship still feels fresh and exciting, and youâre constantly learning new things about each other and having first experiences together. But there comes a point when suddenly youâve done all that stuff together already.
The first day of a period is considered as day 1. Usually on day 14, the egg is released and is waiting for the sperm to fertilize it. The egg has a lifespan of just 12 to 24 hours whereas a sperm can last for about 72 hours in a woman. Sex on day 12 and day 16 is important as it is the time that the woman has the highest chances for pregnancy.
