your bad or good temper ? ask your father
fresh replied to fresh's topic in Psychiatry and Psychology
I don't have any scientific evidence to back it up. it is all from what i observe in life. Is it possible I found this trait inherited from our father before any scientists start to study it ? If I google the evidence, copy and paste here, it is like an assignment instead of discussion. I am curious anyone has the same conclusion of mine from his/her experience ? -
I have to admit it is a speculation, but from what i have observed we probably inherited temper from our father. A bad-tempered person most probably has a bad-tempered dad, while the chance of a good-tempered person with a good-tempered dad is very high. Although I don't have the scientific reference to back it up, i believe it is the gene from our dad. what do you think ?

how to remove yellow stain from white clothes made of pure cotton ?
fresh replied to fresh's topic in Applied Chemistry
it is impossible from the sweat of my hands. all the stains are on back of the clothes. The clothes folded and stacked are never stained before. By the way, it is better to get all the clothes out regularly and hang outside under the sun or it may have an unpleasant smell i can't find words to describe. -

No vitamin D generated without sunshine ?

yes. no need D2, even D3 which is too strong and too much. D1 is quite enough for normal people. -

some washing-powder companies hype that their product can whiten the clothes and make them look whiter than before, what ingredients do they have ? yes, you are correct, only this one is stained yellow and it was white before. Any stain on white clothes would be very obvious and easy to spot. this clothes was washed by hand and put into my wardrobe for more than 6 months before i found it yellow stained. it must have had some mysterious chemical reactions during this duration. -

hydrogen peroxide is widely used in cleansing products and tooth whitening. If i can't get Oxiclean, are other products available ? or does toothpaste contain hydrogen peroxide ? -
I tried white vinegar twice as suggested but it proved useless. i have no idea how these extensive yellow stains appear on my clothes which i don't wear for more than half a year. They are not from food or drink stains, and they have no smell at all. it is so strange this is the only white clothes i found with yellow stains, however other white clothes maintain pure white for years. If i bleach this clothes, is it bad for my skin ? it is a summer clothes. Thanks.

what does "man flu " mean ? cold and flu both are contagious, of course that one person passes it to another is quite normal. it is possible to get cold then flu afterwards from my experience.

fresh replied to fresh's topic in Microbiology and Immunology
I lack of exercise and exposure to sunshine, even though i drink milk everyday & eat food which provides vitamin D, i am still at risk of osteoporosis. is my understanding right ? Bone density test is very expensive; I have a diet that contains vitamin D; I lack of exercise because of my job. I only depend on what I eat to avoid osteoporosis. -
