Song lyrics
Co tak puka, gdy siedzę bez ruchu? Dłoń kładę pośrodku mojej klatki Lekko na lewo czuję: puk-puk Pod dłonią czuję równy rytm To serce — mięsień, który pracuje Dwa palce lekko kładę na nadgarstku Każde uderzenie tworzy falę pulsu Puk-puk, serce pompuje krew Kurczy się, rozluźnia, znów się napełnia Krew pobiera tlen w płucach I niesie go od stóp aż po głowę Robię kilka lekkich podskoków Policzki robią się różowe Znów dotykam klatki i nadgarstka Teraz puk-puk brzmi trochę szybciej Bo mięśnie w ruchu chcą więcej tlenu Puk-puk, serce pompuje krew Kurczy się, rozluźnia, znów się napełnia Krew pobiera tlen w płucach I niesie go od stóp aż po głowę Siadam na kanapie, odpoczywam Mój puls zwalnia z każdą chwilą Puk-puk łagodnie wraca do spokoju Puk-puk, serce pompuje krew Kurczy się, rozluźnia, znów się napełnia Krew pobiera tlen w płucach I niesie go od stóp aż po głowę W spoczynku puls jest znów wolniejszy Serce wciąż pracuje jak pompa
Language version lyrics
What taps while I am sitting still? My hand rests near the middle of my chest Just left of center, I feel thump-thump A steady beat returns beneath my palm My heart's a muscle working all the time Two fingers gently rest upon my wrist Each heartbeat makes a wave I feel as my pulse Thump-thump, my heart is pumping blood It squeezes, relaxes, fills again Blood picks up oxygen in my lungs And carries it from toes up to my head I do a few light, easy jumps A rosy glow comes to my cheeks I check my chest and wrist once more Now every thump arrives a little faster Moving muscles need more oxygen Thump-thump, my heart is pumping blood It squeezes, relaxes, fills again Blood picks up oxygen in my lungs And carries it from toes up to my head I rest upon the couch and breathe My pulse slows down a bit at a time The gentle rhythm settles down again Thump-thump, my heart is pumping blood It squeezes, relaxes, fills again Blood picks up oxygen in my lungs And carries it from toes up to my head At rest, my pulse is slow again My heart keeps working like a steady pump
