Hi! So my dad is in his 60s he drove a truck for a while off and on because he got sick, he is better now but he had a career change he’s retiring soon and he says he always thought about being a truck mechanic. I was wondering if it is too late for him to learn. He is definitely not that healthy but would he be okay if he were to pick up a 2 year course? Like in terms of stress and overall difficulty mentally and physically would he be able to learn?
