Need advice: Should a 40-year-old software engineer switch to a government teaching job?

I'm 40 years old with 15 years of experience as a software engineer. My current in-hand salary is around ₹2 lakh per month. The job is fairly stable, the work pressure is manageable, and I have a decent work-life balance. Recently, I got an opportunity to join as a government teacher for computer science subject, where the in-hand salary would be around ₹1 lakh per month.

If you were in my position, what factors would you consider before making this decision? Have any of you switched from the private sector to a government job (or vice versa)? Looking back, do you think it was the right decision? I'd really appreciate advice from people with experience in either software engineering or government teaching, especially in India.
