I love exercising! It is funny how not too long ago, fitness was considered the mere capacity to carry out daily activities without becoming fatigued! Do you like to exercise?
Before the industrial revolution, "fitness" was defined as the capacity to carry out the day’s activities without undue fatigue.

Physical fitness
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest. Before the industrial revolution, "fitness" was defined as the capacity to carry out the day’s activities without undue fatigue. However, with automation and changes in lifestyles "physical fitness" is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.
Reduced muscle mass, strength and performance in space
There is a growing research database which suggests that skeletal muscles, particularly postural muscles of the lower limb, undergo atrophy and structural and metabolic alterations during space flight. However, the relationships between in-flight exercise, muscle changes and performance are not well understood. Efforts should be made to try to understand the current status of in-flight and post-flight exercise performance capacity and what the goals/target areas for protection are with the current in flight exercise program. From the very beginning of the U.S. human space program, serious and reasonable concern has been expressed about exposure of humans to the microgravity of space due to the potential systemic effects on terrestrially-evolved life forms that are so suitably adapted to Earth gravity.
South African labour law
South African labour law regulates the relationship between employers, employees and trade unions in the Republic of South Africa. The Native Labour Regulations Act 1911 prohibited strikes by trade unions, introduced wage ceilings and a pass system for moving around jobs. Over 70,000 Chinese labourers were brought in, and used by landowners to undercut the wages of other workers. Among white workers, there was significant unrest, and major strikes took place in 1907, 1913, 1914 and 1922  For a period of sixteen years, from 1979 to 1995, several critical developments occurred in the field of labour law in South Africa, beginning with a radical change in the first of these years, when a significant Commission of Enquiry was held, resulting in the establishment of an Industrial Court, which was given extensive powers to mould, change, shape and develop the law.
Motivation
Motivation is the reason for people's actions, desires, and needs. Motivation is also one's direction to behavior, or what causes a person to want to repeat a behavior. A motive is what prompts the person to act in a certain way, or at least develop an inclination for specific behavior. According to Maehr and Meyer, "Motivation is a word that is part of the popular culture as few other psychological concepts are." Motivation theories can be classified on a number of bases:  Motivation as a desire to perform an action is usually defined as having two parts, directional such as directed towards a positive stimulus or away from a negative one, as well as the activated "seeking phase" and consummatory "liking phase".
Physical exercise
Physical exercise is any bodily activity that enhances or maintains physical fitness and overall health and wellness. It is performed for various reasons, including increasing growth and development, preventing aging, strengthening muscles and the cardiovascular system, honing athletic skills, weight loss or maintenance, and also enjoyment. Frequent and regular physical exercise boosts the immune system and helps prevent certain "diseases of affluence" such as coronary heart disease, type 2 diabetes, and obesity. It may also help prevent stress and depression, increase quality of sleep and act as a non-pharmaceutical sleep aid to treat diseases such as insomnia, help promote or maintain positive self-esteem, improve mental health, maintain steady digestion and treat constipation and gas, regulate fertility health, and augment an individual's sex appeal or body image.
Neurobiological effects of physical exercise
The are numerous and involve a wide range of interrelated effects on brain structure, brain function, and cognition. A large body of research in humans has demonstrated that consistent aerobic exercise (e.g., 30 minutes every day) induces persistent improvements in certain cognitive functions, healthy alterations in gene expression in the brain, and beneficial forms of neuroplasticity and behavioral plasticity; some of these long-term effects include: increased neuron growth, increased neurological activity (e.g., and BDNF signaling), improved stress coping, enhanced cognitive control of behavior, improved declarative, spatial, and working memory, and structural and functional improvements in brain structures and pathways associated with cognitive control and memory.
Sexuality in ancient Rome
Sexuality in ancient Rome, and more broadly, "sexual attitudes and behaviors in ancient Rome," are indicated by Roman art, literature and inscriptions, and to a lesser extent by archaeological remains such as erotic artifacts and architecture. It has sometimes been assumed that "unlimited sexual license" was characteristic of ancient Rome; Verstraete and Provençal express the opinion that this perspective was simply a Christian interpretation: "The sexuality of the Romans has never had good press in the West ever since the rise of Christianity. In the popular imagination and culture, it is synonymous with sexual license and abuse."
