Being deficient in sex hormones is not conducive for a long life. It doesn't mean a 55 year old should necessarily have 1200 ng/dL testosterone, but supplementing up to a normal range is a very good idea for bone health, the ability to exercise, and put on a reasonable amount of muscle so that you don't break a hip from falling when you're 65 or 70.
That's the catch though, these absurdly high levels of testosterone have not proven better quality of life. Especially for those who aren't suffering from a severe lack of testosterone (far beyond the aging process).
I didn't interpret their question as hostile, this might be a case of you projecting. You felt enraged at the question, responded hastily and labelled them in a certain way. Try not to do so in the future.
Please don't post like this to HN, regardless of how wrong someone is or you feel they are. If you want to share correct information respectfully, that would be great; not posting is also a fine option.
Unrelated, but while I have you: Could you please stop creating accounts for every few comments you post? We ban accounts that do that. This is also in the site guidelines.
You needn't use your real name, of course, but for HN to be a community, users need some identity for other users to relate to. Otherwise we may as well have no usernames and no community, and that would be a different kind of forum. https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...
I see what you are trying to do, thanks for contributing to the discussion.
Low T levels can massively negatively impact someone's life, if that can be addressed by supplementing testosterone people should be able to do so. If higher levels can benefit someone then they should be able to supplement it also.
