You may choose a better seat along the path so as to walk as needed to relax your legs. Surely you may well prepare for few interesting books to read on the board, otherwise you may carry your device to see a movie, a series, or drama to entertain you so that you may keep away from long tedious journey in most time.   

Hi Mariana. The condition you refer to is known as DVT. The full name is deep vein thrombosis. Try standing up every hour for a couple of minutes. Stand up and down on your toes a few times. I love Casa de Papel. I'm learning to speak Spanish and it helped me to understand everyday dialogue. Orange is the new black is also fantastic. The Crown is a good English drama series. Story of the current Queen of England. Good luck.

I find notebooks and markers are good to pass the time. Maybe you can reflect or draw...
