Why our immunological responses decreases as age progress?

Answer:
I estimate our immunological response increases, probably through age 40 (40--50 for advanced nations), and then declines gradually along with aging.This estimate is from much experience of medical work rather than from any definitive experimental result...As to the reason, well, all mechanisms tend to wear out eventually. In the case of the human body, it tends to get clogged by pollutants and toxins. Proper exercise, plenty of water and good foods will delay this. Bad circulation has an effect on the health of all cells and tissues.Of course, AIDS is the worst possibility in this regard.Yoga, meditation and anti-oxidant vitamins will help.Some lady recently wrote a book called "Cellular Healing" or something like that. This is in the Spirit over Mind over Matter category, one which I have found for SURE is ABSOLUTELY REAL, even an attainment ordained by God for humans.I have not yet read the book, but caught a brief excerpt of this lady on the radio, sufficient enough so that I will find and read her book, even though I am far along the route myself (in both ways, I am 63).I could get a little more technical, possibly mentioning lymphocytes, and stuff like that.But the BEST of all is the answer which I have given. Also the one helpful to most people.Make yourself a raspberry cooler and read it again. Did you eat your veggies today?Chinese also recommend color variety as well as seed, sprout, leaf and fruit, I think. Your grandmother probably has some good advice too

Our bodies immune system just wears out due to pollutions and heavy metals. Cleation therapy is the only thing that will ride your body of pollutions that I know of. Garlic and some other herbs helps also.

You may know that T-lymphocytes (T-cells) are responsible for conferring immunity on our body. Prolonged exposure to antigens reduces the life span of these cells leading to what is called immunosenescence. These antigens, toxins, pollutants, pathogens, etc wear down our immune system.
Autoimmunity is another factor that leads to ageing. There is an increased cell death, called apoptosis, of Tells in advancing years
