Do americans really get that much spam? I don't see the point of this. You can unsubscribe most superfluous newsletters anyway and you have a spam filter. A few intelligently chosen folders and inbox zero is a piece of cake.

I wonder what happens with muscle soreness. Do they get actually get less sore after consistent exercise? Or do you just blunt your nervous system into not detecting chemical signatures of the damage? I'm guessing it's the second case because people here are commenting that after exercising long enough you can still have gains but no pain of muscle soreness.
