Human sexuality is the capacity to have erotic experiences and responses. A person's sexual orientation may influence their sexual interest and attraction for another person. Sexuality can have biological, emotional/physical or spiritual aspects. The biological aspect of sexuality refers to the reproductive mechanism as well as the basic biological drive that exists in all species, which is hormonally controlled. The emotional or physical aspect of sexuality refers to the bond that exists between individuals, and is expressed through profound feelings or physical manifestations of emotions of love, trust, and caring. There is also a spiritual aspect of sexuality of an individual or as a connection with others. Sexuality impacts and is impacted by cultural, political, legal, and philosophical aspects of life. It can refer to issues of morality, ethics, theology, spirituality, or religion. Some cultures have been described as sexually repressive.
Interest in sexual activity typically increases when an individual reaches puberty. Some researchers assume that sexual behavior is determined by genetics, and others assert that it is molded by the environment. This is the nature versus nurture debate, in which one can define nature as those behavioral traits that are due to innate characteristics, such as instincts and drives. The concept of nurture can be defined as the environmental factors or external stimuli that influence behavior, emotions, and thinking. Biological and physical differences include the human sexual response cycle among men and women.
Sexual orientation is an enduring personal quality that inclines people to feel romantic or sexual attraction (or a combination of these) to persons of the opposite sex or gender, the same sex or gender, or to both sexes or more than one gender. These attractions are generally subsumed under heterosexuality, homosexuality, and bisexuality, while asexuality (the lack of romantic or sexual attraction to others) is sometimes identified as the fourth category. These categories are aspects of the more nuanced nature of sexual identity. For example, people may use other labels, such as pansexual or polysexual, or none at all. According to the American Psychological Association, sexual orientation "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions".
The term sexual preference largely overlaps with sexual orientation, but is generally distinguished in psychological research. A person who identifies as bisexual, for example, may sexually prefer one sex over the other. Sexual preference may also suggest a degree of voluntary choice, whereas the scientific consensus is that sexual orientation is not a choice. There is no consensus among scientists about why a person develops a particular sexual orientation; however, biologically-based theories for the cause of sexual orientation are favored by experts, which point to genetic factors, the early uterine environment, or both combinations. Moreover, there is no substantive evidence which suggests parenting or early childhood experiences play a role when it comes to sexual orientation; when it comes to same-sex sexual behavior, shared or familial environment plays no role for men and minor role for women. Research over several decades has demonstrated that sexual orientation ranges along a continuum, from exclusive attraction to the opposite sex to exclusive attraction to the same sex.
Stadler FLIRT (Fast Light Innovative Regional Train) is an electric multiple unit (EMU) produced by Stadler Rail AG. The articulated trainset comes in units of two to six cars with two to six motorized axles. The maximum speed is 200 km/h (120 mph). Standard floor height is 57 cm (22.4 in), but 78 cm (30.7 in) high floors are also available for platform heights of 76 cm (29.9 in).
The FLIRT train was originally developed for the Swiss Federal Railways and was first delivered in 2004. The trains quickly became a success and were ordered by operators in Algeria, Belarus, Estonia, Germany, Finland, Hungary, Italy, Norway, Poland, Sweden and Switzerland. In August 2013, the order book stands at 910 sold units.
A toll-free, Freecall, Freephone, 800, 0800 or 1-800 number is a special telephone number which is free for the calling party, and instead the telephone carrier charges the called party for the cost of the call. A toll-free number is identified by a service access code, from a dialing prefix range similar to a geographic area code, such as "800". The specific service access numbers can vary by country.
The capabilities of toll-free services have evolved as telephone networks have moved from electro-mechanical call switching to fully computerized stored program controlled networks.

A social issue (also called a social problem or a social situation) is an issue that relates to society's perception of a person's personal lives. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.
Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
