You were a busy boy in your early 20s. A Thai chap I know commenced his
Ph.D at age 30. He already had 2 degrees and 2 Masters by then. A
permanent student!
I started my tertiary education at age 28 after having a prior career in
a different field. Two years effective full time at Teachers College
followed by a further 10 years at Uni.
I was about to undertake another career change at age 48 when I became
rather ill and instead saw the end of my working life. Let me assure
you, retirement is much better when you can plan it in advance rather
than having it thrust upon you.
