Heartbeat:
"The one kind of time measurement directly and sensorially available to us is our heart beating. We have a built-in clock. Just close your eyes lying in bed and feel your own pulse or heartbeats. Healthy hearts beat between 60 and 100 times each minute; you're quite normal if you're pulsing 60 to the minute, or once each second of Earth revolution time. So a one-second-of-time heartbeat is a natural time increment that you can really feel."
