walkit.com helps avert looming threat from floating elephants

Grief, Jamie! If we had 31 million African elephants floating over the UK, wouldn't they block out the sun so much that:

• I wouldn't be able to see anything (including the elephants)
• crops would fail
• there'd be so much social unrest the inherent menance of 31 million African elephants would be neither here nor there.

I've been experiencing so many Tube disruptions on my recent visits into London that I've taken to using Walkit to guide me to my destination, wherever possible. Nice work. I've just finished posting about allostasis which suggests that social policies (like transport) have a role to play in promoting our resilience and protecting us from disease. I can see how a policy that supported Walkit would be a genuine contribution to general well-being.
