Royal Mail and Parcelforce plainly and simply sucks.

It's been a long-standing belief, that I've heard in my childhood, ie "eating a bit of dirt and chicken shit in our youth is what made us strong".
There was even a character created in a scifi series called Earth2, dying of an "understimulated immune system, because of too clean environment"

He's got energy enough without 30bn added to his immense wealth.
But this might simple be a way for him to keep profiting from Tesla (via its shares) after he is no longer CEO. And the reason I would never consider buying anything even related to this person.

We just checked out Sawers Deli in Belfast and wow... We tried two sandwiches - two variations on cajun chicken and both were a culinary delight - food that makes you smile!
They are not cheap £9-10/sandwich but they are ~2 times the size of a regular £4-5 sandwich and 10 times the taste.

A friendly note to idiots: you cannot hurt people on the train by throwing rocks at them, because they have double windows and the outer layer absorbs the impact's energy.
You however, can go to jail for trying and that is not a happy place.
ps. I wasn't targeted, I found it like this

Are all lives equal?
If yes, how much any life is worth?
If not, how much are different lives worth?
Not talking about people, now, but rather about different animals:
pets vs pests.
What if someone keeps a pest as a family pet?
