I reckon I'll be too busy being dead to do much else.

Probably travel or just hang out with my 700 pets

Self-sufficient VR can buried in the ground.

Outdoor activities

Retirement is a great time to devote more time to your hobbies. But many people don't develop interests outside of work and family in their younger and middle years, thinking they'll do it after they retire.So, take the time and enjoy life, develop interests, and pursue hobbies. When i retire, i can devote more time to my existing activities and add a few others.

I’ll probably work part-time and volunteer. I don’t think I’ll be able to sit still.

Isn't it sad, that when you have the time and experience for organising orgies you lack energy and attractiveness to actually do it?

Probably volunteer every now and then and do my PhD.

something useful for people in need, I hope

Hopefully I'll have enough in retirement money to travel.

By then I'll have my own workshop and enough time to actually put it to good use.

Maybe spending less time on retrospring. A question every other day and not every day.

Hang out at McDonald's for three hours every morning and complain about whatever
