好古怪及無聊的小主意(1)

(又是另一個本來可以伸請專利的主意來獻世,自己得不到任何益處,唯一最欣慰這點是看到有人善用我的主意,彷如看到自己的孩子快高長大,造福社會。)

小時侯的體育鞋的底常常穿,再入石仔,走路時不舒服。
不過現在想來其實是有益身心健康,特別對長者及行動不便者有複康及行氣活血之效,做法就是在穿鞋時在內隴放入石仔(或小型的波子),如此只要你不怕痛,你就可以邊行街邊做腳底按摩,不知不覺間改善自己的血液循環,而不用專程搭車上深圳去做腳按摩。不過要小心選擇石頭,怕痛的人可選表面平滑一點的石頭,如想效果更好及更快,則不妨選一些表面尖一點的,可謂苦口良藥;另外,要注意不要連續多用過一星期,最好是兩三天後停用一天,以免腳下的皮膚硬化。

Biological idea: Replace the gene of human eye

One often cited argument from creationist is organ as complex as eye can’t be evolved by mere evolution, so eye must be designed from scratch. I would leave open the question how a designed eye compatible with other evolved organs. Unbeknown to most creationist is there are two ‘designs’ of eye, one which that the blood vessel is in front of the retina, another is which the blood vessel is behind the retina; it would leave to immense creativity of creationist to construe the argument why human being is endow with the later, thereby the inferior design? Why would the Almighty Christian God prefer jellyfish over human in the matter of eyesight?
My interest about eye design is not related to the enduring creationist-evolution debate, my interest is about the possibility of engineering a better eye for human being. Since we can transfer the gene from one species to another, why couldn’t we transfer the gene for manufacturing better designed eye from jellyfish to human gene pool? I don’t think anyone could find an argument against improve the eyesight of human as a species. What short term and long term disadvantage would a better eyesight confer to human being?
DNA-engineering offer human being an unique evolutionary advantage over other species: While other species have to use trial and error to find the gene most adapted to the existing environment which cost million animals their lives, human being can test-trial their idea of improvement pool in laboratory and inside computer. So what take other species a million years to develop, we as human only need to take a billion trial inside the computer(that is less than a hour in fast computer.)
So why not try this idea on human?
