Spa day

A few weeks ago friend P suggested we took advantage of an offer at Long Ashes Spa and treat ourselves to a spa afternoon. We got a very good lunch, free use of the facilities, an excellent full body message and a mini manicure and mini pedicure. I chose tropical sunset for my toes. I feel quite glamorous and very relaxed.
Wonder if you could get this on the NHS how much would be saved on treatment of stress, depression, high blood pressure etc?
