This has been going on for at least 60 years. HomeLink and Intervac have been around since 1953, using printed books at arrange person to person swaps long before the internet.
A few years ago, I went 30 days without caffeine to prove to my wife that I could do it. Strangely I did not get any real withdrawal symptoms, just felt a bit flat for a few days.
I did miss the taste and social aspects of coffee. When the 30 days were over I was quite happy to start drinking coffee again.
That is one option. On the other hand, I have 8 - 10 coffees a day. I never get the jitters or caffeine headaches. I guess I just detoxify it slowly enough that I never get to zero caffeine.
Perhaps it is skipping the soft drinks rather than the caffeine that makes you feel healthier?
I've been listening to triplej for about 20 years and as usual there are plenty of songs I do not recognize in the list. That is part of the deal with triplej, no comfort zone of classics and far more new music than you can follow.
There will be a few teeny pop songs in the list but if you listen to a few, you'll see that the range is far more diverse and none of the usual pop artists.
Over the past few years triplej has been doing a lot of work to foster local music, their site http://www.triplejunearthed.com/ is great and you can legally download plenty of good music.
I guess one day my music tastes will crystallize and I'll join the host of others who think that music was best in year X (usually when they were a teenager). I'll fight that as long as I can.
