Wait, you're saying that in the USA you can make a 4 year tour and get 50k per year afterwards for the rest of your life? Or how long do you need to be in the military for that? Is this for all or just for special groups (like pilots)?

but that's not "never too work again" retirement, not what I would aim for

for 3: Please don't mix up WFH and always connected! I work from home but after my hours my work phone stays at the work desk and that's it, I'm seeing mails and calls on the next day, that's soon enough

Pension after 20 years of work?! That sounds soon and great! Could you maybe explain that a little more?
