Thanks, glad you found some value in it. I find it best to ignore trolls who don't actually have anything of value to add to the content in question. Don't find value in my post? Don't like it? Think it's spam? Ok, good for you :P I do reply to valid criticism, but also don't want to spend my time to trying to debate or convince someone of something or "win" an argument with someone who objects to what I am sharing. They have their argument and I don't have to respond to it. I have other things I want to do than argue with people on a blog post. People will be jealous, haters gonna hate, and that's just that. Anyone is free to respond as they wish to anyone else, but don't expect them to be obliged to respond back or argue with you ;)

Singing is good for the psychological/consciousness state of well-being and evokes emotional states. People don't like feeling sad, but with music or singing, a sad song "feels good" you could say hehe. Not sure about the singing to combat potential 5g issues, but who knows ;)
