Pills

Via friend CA, this BBC story:

The natural "high" produced by exercise could one day be available in a pill that targets a gene in our brains.

The Yale University experts say that experiments on mice could show why regular exercise can help people suffering from depression.

Writing in the journal Nature Medicine, they say it could lead to more effective drugs.

Mental Health charities in the UK already back exercise programmes as a way of lifting depression.

I would like more context - is this to be proposed in addition to exercise? Because at face value, it seems like exercise itself would be a good antidote.

Plus, there is some irony in the creation of pills that mimic a result of exercise... though I do acknowledge the legitimate use of the proposed pills.
