Replying to What if time is completely relative to its observer & 100% internal

If an hour passes, some people or animals may feel like its fifty five minuets and some may feel like its one hour and five minuets. No one will ever know how long time actually travels because its an internal feeling, sure you can use a clock but to one observer the second hand ticks every .09 seconds and to another it takes 1.01 seconds, this being an internal feeling. For humans the time we feel may be less extreme because its not noticeable (people operating at flash speed), but for animals their internal time might be far faster or slower. I thought of this while walking home and seeing a humming bird, the little thing operated at such a high speed, but not just the wings flapping (12-90 per second) because that may be a spastic muscle reflex, but the way the bird did everything looking around for nectar & rotating its head.

Thoughts?
