Mens sana in corpore sano, but the question is, how to keep a healthy body in order to keep a healthy mind?
Gyms may be convenient but their sweaty surroundings and mechanised rigour lack charm. Jogging is a good alternative and has the added benefit of fresh air and natural light.
Those who live in the country can bound along track and over fields but those in the city need to live near verdant spaces if they want to make outdoor exercise a pleasure.
Here are a few pads around the world with easy access to parks, some with designated running tracks.
▲ Apartment 2001 Bayou Bend Towers, Houston, US, $4.495m
Where: Near Memorial Park, Houston, Texas.
What: A three-storey, five-bedroom penthouse with a huge terrace overlooking Houston.
Why: This gigantic penthouse is five minutes’ jog from 1,466 acre (593 ha) Memorial Park, the very park that George Bush Snr jogged through on election day 1980. Sportier people will find miles of running trails, as well as other exercise opportunities including tennis, softball, swimming, croquet, volleyball, skating, cycling and the Seymour Lieberman Exercise Trail, a 2.93 mile crushed granite pathway that gets 3m visitors a year.

▲ The Residence, London, UK, £20.5m
Where: Highgate, London.
What: A new-build mansion with seven en-suite bedrooms, near Hampstead Heath.
Why: 800 acre (324 ha) Hampstead Heath is a fascinating place to run. There are great views over London, interesting wildlife and colourful characters day and night. Hampstead itself, a couple of miles north of London’s commercial hub, is renowned as an intellectual, artistic but fabulously wealthy area, with reportedly more millionaires than any other British neighbourhood. For rainy days, the luxurious house has a gym, indoor pool and cinema.
Who: Glentree International, www.glentree.co.uk, tel: +44 (0)20 8458 7311
▲ Unit 89/1 Macquarie Street, Sydney, Australia, A$7.25m (about £4.7m)
Where: Circular Quay, Sydney Harbour.
What: A three-bedroom freehold apartment overlooking the opera house and Sydney Harbour.
Why: This apartment is handy for running tracks that snake all over the harbour side and nearby Botanical Gardens, where you can join the health nuts of the financial capital’s population. It is right by the central business district, where any office job is likely to be. Each marble bathroom has a spa tub and you have shared use of a 25m pool, gym, 24-hour security and concierge.
Who: Savills, www.savills.com/international, tel: +44 (0)20 7016 3740
▲ 19 Clifton Road, Cape Town, South Africa, R50m (about £4.5m)
Where: Clifton, Cape Town.
What: A five-bedroom house on the beach.
Why: Sandwiched between the beach and Table Mountain nature reserve, but just around the corner from central Cape Town, this house has myriad jogging options around the vast reserve, which stretches all the way down to the Cape of Good Hope. Or there’s always the sand. When you’ve finished your run, you can float in the pool and enjoy the view, or slob out in the home theatre.
Who: Chesterton Humberts, www.chestertonhumberts.com, tel: +44 (0)20 3040 8210
2 Trevor Place, London, UK, £17.5m ►
Where: Opposite Hyde Park.
What: A historic townhouse with six en-suite bedrooms and a terraced garden.
Why: Visual and voice identification entry removes the jogger’s constant problem of where to keep his keys during a trot around Hyde Park. Air-conditioning will be a boon on hotter running days, and the elevator will be a godsend to tired legs after longer slogs, for example the 26.2 mile London Marathon. Local restaurants for a jogger’s feast such as Blumenthal’s Dinner and Zuma are among the world’s best. Shopping in Harrods, Harvey Nichols and Sloane Street is excellent.
