Yeah I agree, depression is a bigger deal than those things. But there's also heart disease, obesity, etc that are along the same tier of health issues with massive impact. But the #1 biggest issue imo is the length of commutes. We would all be so much more productive if we would all move to perma-WFH.
If we could get rid of depression a lot of other things you mentioned would go away too. A lot of unhealthy lifestyle comes from lack of clear thinking and escapism.
