I spent many happy hours flying around in that aircraft hoping it didn’t fall to bits! Just retired after 43 years flying, most of it on 737 variants. Great aeroplane.
The only time I experienced pressurisation failure (complete with 'rubber jungle' down the back) was in 'SY, caused by a faulty door seal. We were over the Alps in IMC at the time (MSA 18,000 ft) which complicated matters somewhat.
