like you said we just don't know and untill we have torts living longer on weeds etc with extra light/heat all the modern recomended ways than the torts that we know lived the old fashioned way then we have no way of telling whether the new methods are better or not. We like to think they are because we know more about torts in general but it still hasn't been proven simply because there aren't the cb torts that have been kept that way for long enough yet. I also think that the majority of the older torts were wild caught and may have had either a better start or better imune system than those who are bred in captivity, again I don't know the oldest cb tort and untill we have those figures we still can't say that we have it correct plus every so often along comes someone else with a new way or saying not to give or use what was recomended only a short while before. I do know my Tootsie has a lovely shell, was wild caught possibly back in the 60's or 70's her age is unknown, was fed all manner of things, hibernated far longer than the reccomended times and in a far warmer enviroment, had never had extra heat/light yet is still a lovely healthy tort. I've never had any tests on her as I'd not want to upset what seems ok so I suppose I don't know if she's as healthy inside as she looks but if I ever managed to raise one to look like her I'd be very pleased. Sid my male is uk cb also has a lovely shell and is about 14 he also was fed cooked veg. hibernated as long as he liked in a hutch with no extra protection but again lived outside with no heat/light, he has very little if any pyramidding yet none of the modern methods were followed, it does make me wonder.
