**7. Limitation of the study**

The study was conducted among 15 food/parcel delivery riders, thus sample size was small, which may not be representative of the larger population, as well as bound to a limited generalisability. Moreover, even though the interview was conducted in various locations in Peninsula Malaysia, the results may not be generalizable to other regions.

In addition, the study findings solely relied on the interview answers, which may be subject to bias.

For future research suggestions, it is recommended that a cross-sectional, quantitative study involving a larger sample size could be used to increase the generalizability

of the findings. Furthermore, the study could be replicated in multiple locations to examine regional differences, especially among the samples in Borneo region.

Using objective measures, such as physiological data obtained by using survey questions, is also proposed to reduce bias in the data.
