Not in any order:

Cycling
Bike building & repair - some paid.
Volunteering
Looking after Dad
Visiting daughter in London
Visiting friends/family
Gym
Reading
Travel & holidays
Hill/coastal path walking
DIY
Pub

As little as possible:

Gardening
Shopping
Daytime TV

I always worked to live, rather than lived to work, so retirement was never a problem.

P.S. Just noticed you own no bikes. Have you given up cycling or are you just "between bikes"?
