However, regular work and stair case are contradictory to the same. Don't you think so? I agree that walking or moderate amount of exercise keep everything in the body movin and movement equal life. But, I don't think use of stair case and walks improves your memory. It does improves think out of box knowledge if we walk, jump, and laugh. Questions like: Bay of Bengal is in which state? Liquid. What looks like half Apple? The other half.
I also learned memory booster eatables and vegetables like Spinach, Salmon, Walnut etc. But, it's weired and vague to agree with stair case exersice. I agree that as long as our body moves it is counted as an exercise and there is no connection with brain memory.

We all feel that exercise is good for maintaining our body but it is good for your mind also to keep fresh. Another observation is when we go for a walk our inner mind will be working on some issues which require a solution. Without any other aspect in your mind, if your inner mind is working on some issue, we can find out a solution to that problem. May be this is taken as example and inferred that memory power will increase.
As far as I know walking is a good exercise and same is the case with climbing of stairs.
Orthopaedic specialists, though, advise people with knee pain not to climb up stairs and to avoid it wherever possible as it puts further pressure, but they can climb down the stairs.
Keep smiling...one day life will get tired of upsetting you.
