Circadian Rhythm

There's a really 'interesting' - and perhaps highly controversial - topic of which I want to write (perhaps the correct term would be rant) about here, but I just haven't been bothered to do so, and there are MANY other people with way better arguments on it.


So I was watching part of a documentary on SBS (why must you ruin my world cup experience) on the Body Clock. Apparently, the brain cells composing the body clock are most sensitive - or rather, the eyes - in the early morning around sunrise, and the evening before sunset. Following from this, people who find themselves sleeping and waking too late should go for a run in the morning to expose their eyes to light, and do the opposite in the evening: vice versa for those waking too early.

But at this age, this is all quite chaotic since the circadian rhythm is screwed up by higher melatonin levels. The strange thing is, people doing night-shifts would expect to be able to live normally right? But in reality they have a higher risk of contracting disease, getting cancer, etc. Natural death by old age seems to happen most frequently at this time too. These guys should get a pay rise or something (especially nurses/doctors, who knows how hard they work).

So it seems that 'Heartbreak Hill' has a average gradient of about 6% over 1km. Uh-oh. Also, how to get from school to Museum Station before 7:45am in the morning. LESS THAN FOUR MORE WEEKS! CARDIOVASCULAR MUSCLES HAVEN'T HAD A WORKOUT FOR TWO WEEKS(!)

On that topic, maximum heart rate (MHR) is estimated to be around 220 minus age for young people. Training levels are 60-70% for aerobic activity I think, which is 123-143.5 bpm, while my resting heart rate is 52 bpm (I'm not kidding) which is about 25.3%. Wait wtf that's insane.

People like Alberto Contador have resting HRs of mid-20s and 30s though, so it's all okay.

Anyone here interested in that study group idea? (seriously)
