Your body isn’t disobedient.
It’s badly timed.

Every cell has a molecular clock — CLOCK, BMAL, PER and CRY — running a 24-hour loop that sets your energy, appetite, sleep pressure, metabolism, and mood.

When those clocks fall out of sync with your actual life, you feel it… usually as “Why am I like this?”

This video takes you inside the mechanism:
• how CLOCK and BMAL start the day
• how PER and CRY pull the system toward night
• why the loop resets
• and how your habits shift the timing
