Hi Diago, congrats to your move to Germany, I used to live there too for good number of years.
Before the match - something tangentially related - if I'd have to say what has the biggest impact on my health, then the answer is clear: fasting. I could write long about it, but I think it is the best, if you are interested, to simply look up videos about fasting, I can recommend Dr. Walter Longo and Dr. Alan Goldhammer, e.g. Also about the duration of the fasting - it's better to get to know what happens when in the body first, then decide. My last fast was 6-7 days.
Now heading for a match, yesterday 4 hours match, now again. I play in czech level called "divize", yesterday we won 10:8, and my point was the very last point, tasted sweet, it is only our 2nd win this season, I did 2 wins 2 loses. In CR there are many TT competition levels: Okres 4, 3, 2, 1, Kraj 2, 1, Divize, Liga 3., 2., 1. and Extraliga. Out of curiosity, enumerate those in Germany pls. Cheers.
