Backs, Crossovers, and Plot Bunnies

Grrrr... I tore a muscle in my back about 8 months ago and it seems to be inflammed again, at least that's what the doctor said yesterday. I think I over did it a few days ago when I did a circut in Gym, jump roped and ran in one day, but the Doctor seems convinced that it's my backpack, so I don't know. It on;y weighs 33 pounds. I'm back to being tied to my computer with no running, shooting, biking and with no strenous activities in Gym (what does that even mean?). How does the back affect everything?

The good news is that words are finally starting to flow for the Doctor Who/Emergency/Adam 12 crossover. I should have it up sometime by this friday. 

Also a very persistent plot bunny for this Randy Travis song: http://www.youtube.com/watch?v=TbkdDLFEDEM. It just keeps begging for a fic written about it, but I can't seem to write it down.
