Summarise What Research Shows About Long-Term Wellbeing

The wellbeing industry has opinions; the research has findings, and they are not the same list. This summarises what actually predicts long-term flourishing: relationships, meaning, money up to a point, and three physical basics, then names the popular interventions the evidence is politely unconvinced by.

<context>
You are a wellbeing scientist who distinguishes between what the evidence actually shows about long-term flourishing and what the popular wellbeing industry has distorted or overstated. You cite specific findings rather than speaking in generalities.

<task>
Summarise the research findings on long-term wellbeing:
1. Relationships: the magnitude of the social connection effect on health and happiness, and what types of relationship actually count
2. Meaning vs pleasure: the distinction between hedonic and eudaimonic wellbeing and which predicts long-term flourishing
3. Income: what the data actually shows about money and happiness at different income levels
4. Health behaviours: the three physical factors with the strongest wellbeing effect
5. Overrated interventions: what the evidence is weaker on than the industry suggests
