Nevertheless I recognized that it was wasting huge of amounts of energy for nothing.
The difference in energy usage is probably very small, and certainly not something I'm going to worry about. In fact, using energy through physical activity is a good thing.
Some ppl like the extra flavor of the other cigarettes, which is one of the reasons why there are four brands of cigarettes: One size does NOT fit all.
But how many of those are healthy for you?
Cigarettes are never healthy for you, extra flavors or not.
For most ppl, peanut butter is not harmful.
That's not the point. The point is that different people like and prefer different things. Take computer mice: Some like them heavy, some like them light and some don't care.
For everyone, impacts are harmful.
I don't see how the minuscule impacts from typing are harmful at all.
For everyone, wasted energy is wasted energy.
Having to use a tiny amount of extra force when typing isn't a waste of energy. I mean, how much extra energy are we talking about? 100 KCal? Big deal.
Saving energy is a universally desirable goal when performing work.
Then use a touch screen based keyboard. No force required at all

Staying healthy is a universally desirable goal.
If health is such a concern for you, then you should be looking at ergonomically shaped keyboards, because the way your hands are positioned is probably more important than the small amount of force required to press a key.
Really, I like my Cherry Black keyboard and don't care at all about how much force is required to press down the keys. I have no computer related health issues at all, never had and probably never will. If I want to do something about my health, then I'll stop smoking, start eating healthier and get some regular exercise. This will have a lot more impact than worrying about minuscule amounts of force and minuscule impacts.
Can everyone just use the equipment they're most comfortable with, without saying how it's best for everyone? Thanks
