Angela asked, what happens when payment stops?  What I think is
that if the study/payment is sustained for 3 years and there is
significant difference between control and experimental groups
there will be need to sustain payment or gradually withdraw
payment while at the same time getting the participants to
realise the positive health benefits they have gained apart from
the financial benefit.  Bolajoko Aina
