They way we go for a s*** in the west doesn't help. Sitting upright on a toilet doesn't allow the anus to open properly, causing backups, and retaining toxic chemicals in your stool. Eastern countries where squatting to crap is still the norm, have massively lower rates of prostate cancer, and docs think this is the reason.
It can be combated by taking a small chair, and raising your feet on it whilst sitting on the bog, this open up the anus properly, allowing proper excretion.
