more questions:

1) women have 2 ovaries. do they alternate in ovulation every month? one month this ovary ovulates, the next month the other ovary, and so on?

2) how to gauge if a menstrual flow is heavy or light? i mean... we don't go around comparing the amount with other ladies, do we? Embarassed

3) why dun pesticides not harm humans? or do they, in large quantities?

4) how do hair removal creams work in removing hair? do they.... digest the follicles, or what?

5) why do nearer things look larger than things further away?

6) when you walk for too long a distance, which part of the foot will ache first? why?

7) how does the larynx shape change as we age?

Cool a new kind of spectacles have been marketed. they claim that the lens can focus light from near, intermediate and far away objects clearly (as though you are wearinga 3-in-1 specs). this.... is bullsht right? i mean, it's our cillary muscles and all that inside the eye that does the adjustments right?

Haha...sorry..have been busy with the students. Things should get better in July when I finish teaching my module. Whilst I am here, will try to answer some of your earlier questions..

1) women have 2 ovaries. do they alternate in ovulation every month? one month this ovary ovulates, the next month the other ovary, and so on?

No, quite random although statistically ovulation occurs with fairly equal frequencies on both sides (Ecochard R, Gougeon A. Side of ovulation and cycle characteristics in normally fertile women. Hum Reprod. 2000 Apr;15(4):752-5.)

2) how to gauge if a menstrual flow is heavy or light? i mean... we don't go around comparing the amount with other ladies, do we? Embarassed

The anount does vary between individuals. You can gauge a change in flow by the number of pads used, degree of soak and the presence of blood clots. A lot of blood clots indicates heavy flow.

3) why dun pesticides not harm humans? or do they, in large quantities?

They do harm humans, depending on the type and amounts. Organophosphate pesticides/insecticides are often used in suicide attempts in the developing world (and occasionally in Singapore). They block the enzyme acetylcholinesterase at the neuromuscular junction. Quite commonly used in poisoning cases in agricultural societies and was originally developed as a chemical weapon.

4) how do hair removal creams work in removing hair? do they.... digest the follicles, or what?
The most common alkaline ones contain calcium thioglycolates which break down the disulphide bonds in keratin and so act directly on the hair shafts. They do not penetrate into the follicles deep within the skin that much. Some newer depilatory agents like Vaniqa(TM) are supposed to act on the follicles to slow down hair growth.

Be careful with depilatory creams...some people are sensitive to the high pH and some get a contact eczema.

I want OM to die in the hands of MSK and his minions.

most of the questions that TS asked, could have easily been googled,

likewise OM could have googled it and replied.

as for OM's claim of being a doctor, it's highly dubious.

which doctor you visit, googles your queries for a reply?

when I questioned him about the meaning PQRSTU (in another thread),

he wasn't able to reply.

PQRSTU is the fundamentals of pre-med.

What's the matter, maurizio? Taking potshots behind the skirt of SB when you cannot win an argument at SC? Aren't you man enough to engage in proper debate rather than make personal attacks? I guess not :)

maurizio13 SG

no taking potshots, just stating facts.

basic ECG also don't know, still claim yourself to be a doctor.

if you really are a doctor, I am sure you would have been able to answer my question last time.

in the past, all your answers are googled from the net, these days you have gotten smarter and re-edited them.

don't claim yourself to be a doctor, unless you are one, you are bringing discredit to the profession.

Haha...sour grapes from someone who cannot get through the door of medical school. Don't keep running from lost arguments in SC leh :)

whether or not OM is a real doctor is of no consequence to me. i dun care if he is a real doctor, or if he googled his answers, re-edited them, added in pseudo-sciency stuff in his explanations, as long as they sound credible, they add to my pool of known facts. whether or not, and when, i validate his claims is up to me.

white cat, black cat, doesn't matter. as long as it can catch mice, it's a good cat.

i'll appreciate it if you divert your focus to being a good cat, instead of trying to prove OM a fake cat. you'll be more constructive in the former instance.

OM: more questions.

1) why are some medicines eaten before meals, and others after meals?

2) the left brain hemisphere processes mathematical problems, and images seen by the right eye. if you have a lazy right eye (that is, you usually use the left eye to see things, hence the images are sent to the right brain), will this have negative consequence on your mathematical abilities? cos although there is the corpus collosum (however u spell that) that maintains communication between the two hemispheres, the human brain is highly lateralized to minimize overlapping functions of the brain.

3) my mum says i shouldn't read when i lie down, cos it will cause myopia. how exactly does that work?

4) in a cold, air-coned room, some people have warm hands, some have cold hands. why? if you have hands that get cold easily, does this indicate weak constitution?
