I have not found a way.
However, if you have one monster thread running, clicking on any notification will clear all of the notifications from that thread but not any others. So you do at least have a quick way to get rid of them and you won’t miss anything you care about.
The dose makes the poison. It is carcinogenic but current estimates are that you’d need to drink several litres a day to meaningfully increase your risk.
There are other good reasons to find a healthier drink but this isn’t one of them. Most artificial sweeteners have some kind of risk attached so there is no point switching to a different diet soda.
It isn’t really nature vs nurture, it’s nature interacting with nurture. Steve Jones, the biologist explained it beautifully with reference to Siamese cats:
Siamese cats are light brown with dark brown fur at the tips of their ears, feet and tail. But if you raise one in a very warm environment, they will be light brown all over. A very cold environment, they will be dark brown all over. There’s a gene switching the fur colour but its action depends on the temperature.
There are many different ways genes and environment interact, there’s no real ‘argument’ here. It is simply true and, because genes and environment are often so closely linked, it’s often complicated and sometimes impossible to tease out what’s causing what.
