My Dad, ex RAF, was always smart - fully dressed, jacket and tie etc by 7am every day. He wouldn’t wear jumpers, just agreed to Nordic string vests during the winter. In his last couple of years, we employed a ‘bath nurse’ to help him bathe in the evening, but he insisted on getting re-dressed properly after his bath, as it was only 8pm and he just wouldn’t/couldn’t allow himself to sit round in his pyjamas!
Not too sure about your testosterone theory Oreo
It isn’t a theory it’s a fact.Probably happens biologically to stop older men getting into fights which they would lose😁
