I do and I haven't quit dressing. Testosterone is important to our bodies for more than just sex or feeling "manly". Not being a doctor or trying to pretend I am, I won't go into it but my doctor told me it was important to maintain a normal testosterone level for "quality of life". Since he is a doctor and I am not, I believe him.
The Internet has great value as an educational tool but it also has great risks. If I wanted to, I could set myself up as some qualified doctor or researcher and publish opinions on just about anything. Nobody would know the difference.
We can explain how a car engine or an electric motor works scientifically. We cannot do the same with the human mind.
