You see in this world there's two kinds of people, my friend. Those with loaded guns and those who dig.

只要经常出一身汗，这不是问题，关键是老年人出一身大汗的机会少在路上 写了： 2025年 5月 15日 16:34 老人味（日语：加齢臭，かれいしゅう）是中老年特有的体味的俗称。[1]
2000年12月11日，资生堂研究中心研究员土师信一郎等人发现了高龄者体味的一个原因是叫2-壬烯醛（C9H16O）的成分。这种体味成分有青草气味和油性的气味。这种气味不但有男性的体臭，而且本来在老年女性的体臭研究中，这种成分也被发现。
主要是四十岁以上的男人会有这种成分在体中形成。棕榈油酸（9-十六碳烯酸）是发生壬烯醛的成分。单纯的9-十六碳烯酸没有臭味。但是把9-十六碳烯酸氧化分解后就会产生壬烯醛。不纯的9-十六碳烯酸会发出蜡烛、乳酪、旧书那样的臭味。吸烟者比不吸烟者所释放的这种体臭更为浓烈。为了抑制壬烯醛，抑制壬烯醛的基本成分脂肪酸分解氧化还原剂和抗菌药很有效。用机能性香料或者明矾溶液一定程度上能抑制加龄臭。
雄性荷尔蒙促进皮脂腺发育，增加皮脂大量分泌。结果，老人味的原因成分壬烯醛就大量发生，因此有一股老人味。雌性荷尔蒙有一种氧化抑制的效果，因此脂肪酸不容易氧化，所以女性几乎没有老人味。
狮王对从二十几岁到三十几岁的男人特有的体味进行了研究。根据这个研究结果，主要2-壬烯醛（C9H16O）臭味不同的壬酸是老人味的主要原因。这个物质主要在三十几岁的男性中明显增加。
这是关键，在健康允许的情况下，老年人经常进行运动直到到出汗，对抑制加龄臭帮助最大

可能他肝肾功能处于临界状态。每天日常工作产生的代谢废物就够内脏勉强应付的了。
再锻炼健身，肌肉产生的额外废物肝肾会受不了的。
先从调节饮食入手吧

Grok answer:
The phenomenon often referred to as "old man smell" isn't exclusive to men. It's a body odor change that can occur with aging in both men and women, driven by similar biological processes. As people age, hormonal shifts, particularly a decline in estrogen and testosterone, alter skin gland activity, leading to changes in sebum and sweat composition. A key factor is the increased production of 2-nonenal, a volatile compound formed when omega-7 fatty acids in skin oils oxidize. This compound, described as having a greasy or musty odor, was identified in studies like one from the Journal of Investigative Dermatology (2001), which found 2-nonenal levels rise significantly in people over 40, regardless of gender.
Lifestyle, diet, hygiene, and environmental factors also play roles. For example, older adults may use different soaps or have reduced skin cell turnover, which can trap odor-causing bacteria. Women, like men, can experience these changes, though cultural factors—such as women being more likely to use scented products—might mask or alter perceptions of the smell. There's no evidence suggesting women are immune to these aging-related odor shifts; the stereotype of "old man smell" likely stems from social biases rather than biology.
So, yes, older women can have a similar aging-related body odor, though individual variations mean not everyone does, and it’s not always noticeable. If you’re curious about specific cases or mitigation (like diet or hygiene tweaks), let me know!

所以前面引文里说的“雌性荷尔蒙有一种氧化抑制的效果，因此脂肪酸不容易氧化，所以女性几乎没有老人味”不对？smallstone 写了： 2025年 5月 16日 01:49 Grok answer:

跟性别无关，中性人，双性人年轻的时候也没有这个气味。这种描述的老人味类似于停尸房的尸臭，家里死过宠物的可以想象发现宠物意外死亡时全身都是蚂蚁苍蝇的那种气味。

我一个大男人不仅负责赚钱，开车、修车、割草、砍树、买菜、做饭、洗衣、倒垃圾，带娃，什么都要做。
做为男人， 真命苦， 下辈子选择做一块石头
