i just wanna give a shout out to my dear sister lynn who was baptized this past Easter Sunday... i'm rejoicing with u! God-willing, we'll be seeing more of each other in the future... *ahem* t-n--l- *cough* ;)
insulin-resistance and its contribution to aging
key point: too much insulin in the blood has profound pro-aging effects
let's start with the basics:
- carbohydrates are made up of glucose molecules
- when glucose enters the blood, within minutes your pancreas secrete the hormone insulin
- why? - to get the glucose out of your bloodstream and into your cells ASAP
- how? - your cells have receptors (like trapdoors) for insulin; a cell needs insulin first (via receptor sites) in order to be able to absorb and metabolize glucose
- as you age, your cells lose more and more of these insulin receptors
let me use this example:
a five-year-old and a fifty-year-old each have a scoop of ice cream
- little insulin secreted
- sugar quickly cleared from blood
- insulin levels quickly return to normal
- a lot more insulin secreted (to make up for the delay in finding the few insulin receptors that are left)
- sugar takes longer to be cleared from blood
- insulin levels take longer to return to normal (ie. more insulin in the blood for a longer period of time)
again... so what??
when your insulin levels are high:
- your body is adding fat onto your waistline
- your blood pressure goes up
- your triglycerides go up (triglycerides are what make up body fat, like how glucose molecules make up carbohydrates)
- you feel tired all the time (because it takes longer to get glucose into your cells; remember that your cells use glucose as fuel, and a slowed-down metabolism of glucose means that your cells aren't getting all the fuel that they need to function top-notch)
- your kidneys retain salt and fluids, which further elevates your blood pressure
- your arterial walls get thicker and harder -> a precursor to heart disease and poor *peripheral circulation (*in other words, blood has a harder time circulating in your skin and you slowly lose your skin's radiance and elasticity, resulting in wrinkles)
are you scared of insulin yet? there's more:
- as long as insulin levels remain elevated, the effects will override your dieting efforts and make it nearly impossible to take off fat
- any intake of carbohydrates will trigger the production of a LOT of insulin to carry out what used to be a small clean-up job (back when your cells had way more insulin receptors)
- a LOT of insulin will of course linger in the blood longer than a LITTLE insulin
- as time goes by, blood sugar goes up and stays up longer because the cells are doing a poorer job of bringing in insulin... and the result? even more insulin is produced!
what does a high blood sugar level lead to?
- GLYCATION - one of the biggest reasons we age
- when glucose levels are elevated in the blood, glucose attaches to proteins or DNA instead of being utilized as fuel for energy
- this irreversibly compromises the function of the protein or DNA (that is, the cell won't work like it originally used to, and this degeneration promotes aging)
last but not least, insulin's extended presence:
- activates cholesterol-making machinery
- did you know that eating red meat has a relatively tiny effect on your cholesterol levels compared to that of a moderately (not even highly, but moderately!) elevated insulin level?? the cholesterol you eat is only responsible for 20-30% of your circulating levels; the rest is manufactured courtesy of insulin!
- the key point is that eating carbohydrates ultimately has more impact on your cholesterol levels than eating high-fat foods
conclusion: insulin-related metabolic changes foster aging and associated major degenerative changes such as obesity, heart disease, and type 2 diabetes. simply put, insulin has a great deal to do with how gracefully or poorly you age.

"In 1767, Thailand was at war with the Burmese and a champion [Thai] boxer Nai Kahnomtom was captured by the Burmese king Angwa. King Angwa called for a boxing match, the first Muay Thai match outside of Thailand and Nai Kahnomtom defeated all ten Burmese challengers in succession, with no rest at all between the ten fights.
"As a result, Nai Khanomtom was honored as The Father of Muay Thai and the day of the fight, March 17th is now officially named ‘Muay Thai day’ in Thailand."
what are the chances i'd discover that today?? so yah, i figured recognition of muay thai day ought to take precedence over st. patrick's day... on my blog, at least :)

SICK!! SICK!! TONY JAA IS SICK!! DAYAM!!
i cannot remember the last time a movie has taken my breath away like ong bak. and i don't mean screenplay or cinematography or special effects or whatever... i mean tony jaa and his moves. period. the "no stunt doubles, no computer graphics, no strings attached" tony jaa. dayam! i couldn't even sit still throughout the movie... haha, u shoulda seen me on my couch flinging my elbows and legs around and heard all the ruckus i was making... i got sooo totally into the action! beautiful! the elbows, the knees! the elbow-knee combos! on top of the stunts and everything else! holy crap, the skills!! amazing... the guy just blows me away!! i gotta give mad props to muay thai (someone should be pleased to hear that :P) cuz tony jaa really knew how to bring it! if u're into martial arts or action and u haven't seen ong bak, GO SEE IT!!

there was this song that came on several times in the movie and even during the credits (i think the first time it came on was when the bride was being given her sword) and when i heard it, i was like, hey i know that song! i love that song. it totally brought back memories. but i dunno what it's called. i first heard it in regina... channel 4 (cbc i believe?) used to run this short animation thingy between programs and they had this one animation about a bird... two birds actually... one bird was plain-looking and the other bird was grand and beautiful, and the plain-looking bird wished that it could look like the beautiful bird. the whole thing was so sad... the bird trying so hard to be what it wasn't because it couldn't see its own beauty. anyway, that song was the background music for the animation and i fell in love with both the song and the story. (there's something about the song that just makes me wanna cry... maybe it's that beautiful pan flute playing.) i've wanted to know what the song was called but it's been a decade since my regina days and i've forgotten about it til now. i suppose i could just look it up on the net... but i probably won't. i'll just continue to let it be that mystery song i love so much :)
let me know :P
