I am hurt. 

Two friends of ours, invited us to play tennis with them at the local police headquarters. They are spending their summer there participating in a special program. (They are hungarian, forgot to mention)

Anyway, the tennis courts were empty, so we went there to play, as we had never played tennis before. The game was alright, it took some time until I got some practice.

The only downside of the court was the concrete ground, which eventually "gave me a headache".

Reaching for a quick ball, I had to run backwards, when accidentaly I fell off. First I landed on my butt, then hit the ground with the back of my head. 

Of course it got swollen instantly, and started to bleed. For some seconds I was dizzy, but after recovered, and couple minutes later we played another two games.

Today I still have a slight headache, but nothing serious, however I feel terrible pain in my muscles. Let's be honest, after years of only sitting around, with completely no excersize, what the feck I expected? :) We played 3 hours of tennis, which was really intense, so I got myself fully exhausted. 

Today I use the office chair to move around, if I can roll myself to another table I do it, instead of walking :)

My head is still bigger then it is originally, but hopefully it will go away soon.
