This is an argument that came up between me and my colleague last night. Jobs that requires more use of brain like manager, accountant, lawyer, architect etceteral and jobs that require physical power like carpenter, labourer, gateman, driver, e.t.c.. which drain more energy in the long run?

I think its d mental job, cos d brain consumes high amt of glucose, which is d only source of energy for the brain. When u carry out mental task, d brain consume high amt of glucose in ur body to meet up, there by causing both physical n mental fatigue.

But physical job only causes physical weakness.(tired)

Stress is a more severe condition than physical weakness or being tired.
