When Things Go Wrong

Why is it that things always, without fail, go wrong exactly the moment you need them?
Regs work perfectly for months, until 24hours before the dive holiday. Wetsuits that suddenly shrink the week before. Is it fate or is it more likely that we never check stuff until the last minute. Whats the result ? Usually the only person affected is the poor old service technician who has to get the job overnight! So spare him a thought and ease the pressure on yourself too - check your kit!!!
