Stress Relieve for the Life Science Student

when i jog, this is what goes through my mind:

electrical signals sent down neurons
electrical signal reaches pre-synaptic membrane
neurotransmitters released into neuromuscular junctions
motor plate membrane gets depolarized
signal transduction down t tubules
gates at sarcoplasmic reticulaum opens
ca2+ions rush in to muscle cells
ca2+ binds at troponin
tropomyosin moves
myosin head binds onto actin filament
atp hydrolysis @ myosin head
myosin head rotates,actin filament slides
ca2+ resequestered into sarcoplasmic reticulum
atp binds at myosin head
myosin head releases actin filament and cycle repeats.

FATS (and glucose) breakdown is needed to produce ATP, which is required to pump ca2+ back to sr and repolarise membrane and return myosin head to normal position


this is what motivates me to exercise(=
well jogging today was fun albeit the muscle ache i had. while resting to stretch and watching a squirrel scurry on a tree, i heard sth like "PAM!!" so i turned...



to see SHERRY BERRY. oh my long lost friend! she was practicing for 21km stand chart run, and had ran 1km before bumping into me and stopping to chat MUAHA(: after a quick catch up she had to continue with her run lest her partner (who overtook me some minutes ago) catch up with her!!

walking alone was nice, with the breeze in my face, threatening clouds overhead, cute old people exercising, men fishing, hot guys jogging (actually there were none today, but there was a cute guy ytd haha), pretty girls running (guess who?... ME LAH.) then....




KOO SI XUAN! haha my super funny crazy sweet sixteen churchie! she was running in my direction and i decided to retrace my steps. we spent the next hour or so walking and talking it was FUN! conversation topics ranged from campus superstar (go check her out in i zhou kan), NSK thinking that we cant speak chinese, marriage, dog-with-tongue-about-to-drop-off, being anorexic (no we are not), how fats clog up pores (her weird theories), church stuff, her brothers, washington wellington boots, ang ku kueh and chee kueh...

ok we were obviously getting hungry.

and time for me to head home i spent 3 hours at the park cant believe it! but it was enjoyable!(=

ok goodbye time to study about PLANTS:(
