I know many people in their 50s who are Boomer as fuck.

Nicotine.

I stopped counting when my last nicotine hit was, which I think might be the key here. A couple of years at least.

No urges, never even think about it.

When I used to work in the office I probably worked about 5 hours a day at most. The rest was spent on personal projects, fucking around, whatever

Now that I work from home it varies between two and four.

My production is exactly the same.
