Introduction Is happiness or subjective well-being just an event, or does this observable circumstance have responsibilities that go beyond what is experienced by the person who perceives feeling happy? We all want to be happy, but how do we achieve and sustain this goal? Are there predetermining factors that play a role, such as our genetic makeup? The following essay will explore subjective well-being in general, as this is considered synonymous with happiness. An explanation of both the sustainable happiness architecture model and a clear definition of the biopsychosocial model will be provided. Throughout the essay, examples of the SKD228 module will be provided as supporting evidence with possible links to biological factors. The essay will conclude on the compatibility or otherwise of the architecture of sustainable happiness with the biopsychosocial model. (133) Subjective well-being Our time spent is made up of 5% individual circumstantial contributions such as relationships, financial situation, employment, etc. Life experiences contribute 10% to our levels of well-being. Human beings adapt to life circumstances and events. (Boniwell and Rostron, 2010, 134) The subjective report of well-being is not only about how one feels about life satisfaction, but also about one's self-perception. (Boniwell and Rostron, 2010, p134) Throughout our lives we have both positive and negative life experiences that affect our happiness and the hedonic adaptation theory of life satisfaction suggests that we will return to our baseline very soon after one of these events. Huppert suggested that good health and especially subjective well-being are associated with positive emotions, limiting and containing negative emotions. (Huppert et al,...... half of the article...... in two interacting regions of the brain. (Toates, 2013, p34)(345)ConclusionIn conclusion, although these are two different perspectives, try to understand the concept of human well-being and happiness in general; it can be argued that the biopsychosocial one could be more scientific by introducing a more in-depth biological aspect. In principle, the two perspectives are compatible, as they base well-being on the contribution of different factors and a change in one of these factors has a consequence. In the biopsychosocial model, biological, psychological and social factors are interdependent and a change in one can have a huge effect on your well-being and happiness. Sustainable happiness, you have your genetic levels. basically, life events but also your intentional activity that can increase your well-being and happiness.(118)
