I am writing on behalf of a 90 year old student in my Senior chair yoga class- very gentle. He is very stooped over but enthusiastic. The class is unfortunately scheduled soon after breakfast (I have no control over that timing). He reported to me yesterday that every class he finds himself belching the whole time (quietly, so not to disturb the others). This does not happen on any other day but Yoga. None of the other residents have this occurence. Any insight?
