This is an Oak tree outside of my house that is estimated to be over a hundred years old. I spent a lot of my youth playing around that tree. Unfortunately, it is sick and may have to be cut down soon :(. But still love the trees in your neighborhood they give you oxygen!
Are you getting enough Vitamin N? Here is a great article showing the benefits of getting outside and involved in the outdoors. Nature is what we have inhabited for the majority of our human evolution so its benefits can only be so obvious. We should return to that space of naturalness (ha-ha). Anyways hurry up and read the article so you can go outside (I don't care if it is raining, bring an umbrella!).
I really like this article. It talks about being mindful. I don't think many people even remember what mindfulness is anymore. Yes it is being in the present, but it is also being conscious of your surroundings. There is a difference between daydreaming and sitting in a room versus sitting in a room and taking note of the smells, the noises, your physical feelings. Maybe the way your feet touch the ground or how your arms are crossed. Or how your breathe rises and sinks, slowly. There are so many ways to take notice of the present how can you not just be here now? And then there's thoughts. A trap we can't help falling in to. Our society is thought-based. From the moment we enter school, it is all about using our minds for memorization and comprehension and analysis. All things that require you to think back so that you aren't actually here. Anyways, I will probably just do a post on this subject, but in the mean time enjoy someone else's words!
