In big-picture terms, wellness sounds like a pretty good idea right about now. Around the world,obesity rates are climbing (astoundingly, the planet’s “1.6 billion overweight and obese now outnumber the malnourished by nearly 2-to-1”). Noncommunicable illnesses such as heart attack and diabetes have supplanted starvation and malnutrition as the world’s leading killers. Fast food proliferates globally, which is really not helping. Throw in the fact that our choices, as a species, are turning out to have some pretty nasty consequences — things like, oh, endless wars and our own extinction — and the desire to make this life as pleasure-driven and meaningful as possible seems fairly understandable.
