Yep, I second that. Sitting on your bums all day is not good, whether at work or at home. Get up and go do something for 5 to 15 minutes every hour or so. This simple trick can help with your blood pressure, heart and blood sugar levels. This is no joke.
Seriously though, maybe the best tweak is exercise?
I posted, mostly in jest, before that cleaning your gear would yield fantastic sounding results. Yes, it was a joke, brought about by the fact that I thought the sound was better afterwards. Of course it was probably placebo ... but what if the actual cause is moderate exercise?
So, audiogoners, I challenge all of you to go out, put some bug spray on, and put your fancy iPhone or Android HR monitor to good use. Then sit yourself and your sports drink down and listen.
Does it sound better?
