Ouch! My back!
I have had to slow down Arabic-learning in the past few days because my back started acting up badly enough that I started medicating. I am fairly often on my laptop these days, either writing long texts or clicking away. I used to think I was comfortable enough on my kitchen chair to do this. As I use Duolingo, I have to constantly switch between typing and clicking and that has become a problem for the last week. This morning, I ended up borrowing my brother's desk chair to see if it will alleviate the problem. I never thought that learning Arabic was going to be an ergonomic issue. :o)
