Especially at the beginning, research has focused on arguing for the negative effects depending on several variables, (gender, age, sports, etc) at physical level: high risk-taking levels produce lesions and even death [16,24,26,37], sleep disturbances [28], but also pathological personality disorders (narcissism, anxiety, neuroticism, addictions), corelated with compulsive and deviant behaviours (pathological abuse and addiction to drugs, alcohol, sport) [2], [14,15], [29], [38].
