Janine was very active throughout her early adulthood and maintained a very high fitness level. if she wants to maintain this fitness level throughout her middle adulthood, how might her participation in physical activity and exercise be impacted?
(a) janine should reduce the amount of time she spends exercising because it is easier to maintain fitness levels as you age.
(b) janine should keep her current exercise program because, once a high level of fitness is reached, it never changes.
(c) janine should increase the intensity or length of her exercise programs because it is more difficult to maintain high fitness levels as you age.
(d) janine should stop exercising completely because it is not safe for middle-aged adults to exercise.

(C) Janine should increase the intensity or length of her exercise programs because it is more difficult to maintain high fitness levels as you age.

Explanation:

The text states that, Janine has been very healthy during the time she has been an adult. If she wants to maintain this fitness level throughout her middle adulthood, she should work even harder and excerise for more hours daily. Doing so will increase her ability to stay healthy long term and become stronger each time she works out.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.
