Does age matter when you apply for a teaching job abroad? I am 61 years, have been teaching for 17 years and in excellent health

I am a fully qualified English Teacher ( First Language ). I have 2 degrees ( B Paed; B Ed ) and a Post-graduate Diploma in School Library and Resource Centre Management. I've been teaching u English, Art and Library Education for 17 years to grades 8-12. I got into my own business ( Restaurant ) and then into Financial Planning and Advice. I am looking to get back into teaching but am worried about my eligibility. Thank you. Dave Ganas
