If someone is going through something major in their life it can be really beneficial for them to talk to someone who can help them through it. Good mental health is important. If one is depressed for example, that can cause physical symptoms as well.
I have a roku, I like it a lot. Some of cable channels have their own "channels" on like A&E, the history channel and I think comedy central just addd one. So between the subscription services and the free things it's great.
