Translation of heucheln

I really worry about the health of obese people, especially the ones that I know in person (friends, relatives), because it is well known that overweight have a higher probability of heart attack.
I even put on my Poncho, a plastic rain coat, in order to protect myself from the aircon-breeze. Somehow I managed to fall asleep and woke up at around six in the morning when we approach Palenque.
We checked in, took a refreshing hot shower and were really happy about our accommodation. As it was late, we took another ride to some restaurant. When we payed the driver he told us that he had no change.
