A death in the family can cause people to get depressed and turn to habits they don’t generally abuse such as drinking to much this in turn can make it so people get addicted to things like alcohol
It could be true but it depends on the person. Strength training may make someone feel better about their body and therefore boost self esteem but for others it may not
An individual's finances can affect the means by which they can do physical activiry, which in turn affects their ability to keep physically fit.
If, for example, an individual has a small amount of finances to their name, they may not be able to access specialized equipment that would normally be found in places such as gyms (which require a paid membership most of the time).
In short: There's only so much one can do for free and without any kind of fitness equipment.
