People of Reddit, What do a lot of people do currently that will turn out to be really unhealthy in a few decades?

1. I don't move nearly as much as I should. I sit all day at work. I sit in the car/on the train. I walk into my house. I sit on my bed. I sleep. Shit, I really should start moving more.

2. Too much stress and anxiety without enough relaxation and exercise.

3. Putting *everything* online. Aside from the privacy issues -- which, you know, are pretty substantial -- I think the constant stress from comparing every aspect of your life with everyone you know *all the time* is going to have real impacts on people's long-term mental health. Fear of missing out is already a huge deal, and I don't see it getting better any time soon.

4. Hmm. I think we'll eventually realize that our work culture is terrible. We'll find a compromise somewhere that better suits families and personal quality of life. At least, that's what I hope, maybe I'm being optimistic.

5. Not sleeping enough, it's already well established that chronic sleep deprivation is as harmful to pretty much every aspect of your health as "bad habits". Living in big cities too

6. The constantly-connected culture and it's effects on people, and not just kids. With cell phones and texting, plus other apps like FB and Slack, people, especially in certain employment sectors, are expected to be available 24/7. My dad has a business job where he's expected to text and check email while driving. The concept of planned days off seems to be disappearing for lower-income workers, as you can be called in at any time and will be negatively judged (or just fired) for not giving up your day off. Yes, like everything else in this thread, this has always existed in some form, but the constant connectivity is letting it creep into industries it didn't exist in before, and it can be insanely stressful.

7. Essentially everything - Even breathing the air in a lot of places; "oh, wow, living by that motorway for 18 years growing up sure did a number on your respiratory system; who would have guessed?"

8. Energy drinks haven't really been in circulation long enough to see the long-term effects of heavy usage. I suppose we'll find out. Edit: And yes, since some of you asked, you can PM me about your worries. :)

9. Posting on reddit a lot turns out to have a negative impact on mental health.

10. With VR slowly becoming more commercially available through headsets and smartphones, I'm curious to see how those with addictive personalities will be affected psychologically. I'm sure many have heard of the extreme cases of Video Game addiction, especially in competitive play and MMO's; I wonder if perhaps we'll soon start seeing news stories of people who neglected their health through VR addiction, or worse, users who become so immersed they can't distinguish between the subconscious and the conscious. I've already seen stories on /r/Oculus where VR is causing vivid dreaming, and those who had to pause in 'real' life to establish it is indeed real (i.e. waking up and staring at their hands for several minutes). If it is legitimately going to be a problem, I then wonder how the improvements in technology will potentially exacerbate it further, both psychologically and socially.
