At present, there is more than 70 years between the time of the Second World War and ours, that of present events (Tokyo Defense). I do not know Yoshimura's age when he met Kaiko, but I would give him around thirty, and Kaiko still looked the same at that time. Maybe the toxin causes something other than an increase in the life expectancy of the Half-human and change their physical trait somewhat because Kaiko does not look "human" finally this is only my opinion but V agents look similar when they use their Kagune with their black Kakugan. We will have a confirmation to all this in the next chapter without a doubt. But after all, nothing prevents Half-humans to have an aging in their physiology even with their toxin, but I think that the toxin "deforms" them (DSL I did not find other words to describe this)
