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.

Most womenâs menstrual cycles last about 28 days, from the first day of their period to the first day of the next period. Because the egg can survive for 24 hours after ovulation and sperm can live inside a woman for up to five days, a woman can get pregnant starting five days before ovulation and ending a day after.
