Low Backache

I am having backaches after falling down from the bike a week ago.  I fell with goldfishes I bought.  Today, some of the goldfishes died.  Maybe it take a week for the shock to take effect.  It also may be the carbon I put in.  The carbon was in my fridge for a few months.  It had absorbed lots of bad stuff in my fridge.  So I took out all the carbon.  I hope my fishes will continue to do well.  The dead fishes became food for my arowana.

I am doing core muscle exercise to strengthen my trunk.  I hope I will recover soon...
