ABSTRACT
This chapter discusses some so-called lifestyles that can be defined as “patterns of behavioural choices made from alternatives that are available to people according to their socio-economic circumstances and to the ease with which they are able to choose certain ones over the others”. It focuses on sports and physical activity as well as nutrition. The chapter also focuses on the aspects of sexual life directly linked to health; however, one should never forget that adolescents who are not sexually active are still sexual beings, and sexual experience and intercourse is just one aspect or dimension of sexuality among those teenagers who are sexually active. The development and acknowledgement of sexual orientation plays an important role in the formation of adult identity. Adolescents suffering from chronic diseases and/or disability often face difficulties in integrating a defective body within their sexual development.
