My hobbies are (or were) as follows but not in any particular order:

• Large, fast, powerful, safe and comfortable cars;  as in 'space, grace, pace'.

• Computers.  No games, no Internet.  (Except this for RodLog).

• Old and classic films, mainly black-and white.

• Gardening.

• Sailing.

• Reading.

• Scientific TV documentaries.

• HAM radio including the ‘RodLog’ logging system, the G4TUG experimental all HF Band Aerial, an article about Magnetic Loop Antennae and an article about the Noise Figure of Receivers and Pre-amps.

• Tinkering with all things mechanical, electronic, electrical, electromechanical.

• Dieting. Not exactly a hobby but more of a necessity.
