why do old people smell weird?

Answer 1

Because they are just old and stagnant...you know...like an old book. Just sort of old and stale-like. Take a mushroom, pee on it, then smell it in 20 years....its the same thing, no?

Answer 2

A pheromone is any chemical or set of chemicals produced by a living organism that transmits a message to other members of the same species. There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology.
Pheromones in humans. The best-studied case involves the synchronization of menstrual cycles among women based on unconscious odor cues (the so called McClintock effect, named after the primary investigator). This study states that there are two types of pheromone involved: "One, produced prior to ovulation, shortens the ovarian cycle, and the second, produced just at ovulation, lengthens the cycle". This is analogous to the Whitten effect [1] [2], a male pheromone mediated modulation of estrus observed in mice. Other studies have suggested that people might be using odor cues associated with the immune system to select mates who are not closely related to themselves.
Human pheromones are postulated to be produced by the apocrine glands. The apocrine glands become functional after reaching puberty which, it is hypothesized, could contribute to people developing a sexual attraction for others at that time. Pheromone detection has also been proposed to be the reason why a person can sense "chemistry", or feel an instant attraction or dislike when first meeting someone. Using a brain imaging technique, Swedish researchers have shown that homosexual and heterosexual men respond differently to two odours that may be involved in sexual arousal, and that the gay men respond in the same way as women. This research suggests a possible role for human pheromones in the biological basis of sexual orientation.
Androstenone (5a-androst-16-en-3-one) is a steroid found in both male and female sweat.

Depending upon who is doing the smelling, it is reported to be an unpleasant[citation needed], sweaty, urinous smell, a woody smell, or even a pleasant floral smell. About 60% of adult males and 40% of adult females cannot smell androstenone, but some people who initially cannot smell androstenone can learn to smell it by repeated exposures to it.

Androstenone is the first mammalian pheromone to be identified. It is found in high concentrations in the saliva of male pigs and, when sniffed by a female pig who is in heat, results in the female assuming the mating stance. Androstenone is the active ingredient in BoarTaint, a commercial product sold to pig farmers to test sows for timing of artificial insemination.

In humans androstenone also has been suggested to be a pheromone, especially as a supposed sex attractant, but scientific data to support these claims are scant.

Thats simple , old people dont have hormones like young people and their atraction smell doesnt work anymore....

Answer 3
