Combined level 5 TEFL

Don't overthink!
Start asap and dont leave large gaps between units. The course was challenging but satisfying.
Would it be true about regulating the TEFL course by having to do a revision of 100 hours after 2 years of completing the course?
I would certainly be more truthful about age and qualification limitations to successfully secure positions.
How would one secure online teaching positions at age 58 with 21 years teaching experience. 2 months down the line and still no secure positions.
I look forward to travelling overseas to teach. I would love to travel using TEFL at my age because it's do able rather than waitressing as an alternative to make money while travelling.
How many other older people do this? And what is the success rate?
