No idea what's the deal with the second and third ones lol.

But when DH was in primary school he had issues with a bully, so his parents bought him a big heavy bag, and told him whenever it got to too much to go and let out all his frustrations on the bag. He spent a lot of time out in the shed lol.

My Mum got one when I still lived there, it was hung in the shed. I used to turn the music up loud and just go my hardest! Was very therapeutic at times.
