You don't want to wear your life jacket? Fine. I respect your
decision. Wearing a life jacket is cumbersome, not many people
realise that.
BUT
If you fall into the water, and (choi!) drown.....not our
parsah.
It doesn't help that to wear a life jacket properly, you need to
wear it fairly tightly and thus it restricts your movements a
little, but also not to the extent many people claim. If you don't
make it tight, you sink and the life jacket floats without you.
I do remember putting one on during one of my camp outings in
secondary school. Had to wear one, they brought us swimming at one
of those quarries in Ubin. I never found it cumbersome or very
tight.
