I believe it would be C. Cracking a rib.
Because
- CPR doesn't involve the arms
- Headaches can happen at any age
- Not finding a pulse can happen with any person
- Cracking a rib would make the most sense to me due to that bone mass or density decreases as a person ages, the bones lose calcium and minerals causing them to deteriorate and become more brittle, which may result in them becoming easily breakable.
This is only my guess though, so don't take my word for it.
Hope it helps at least a little. (:

Including lifestyle activities in a personal fitness program can be beneficial because it increases the total amount of time spent on fitness activities in a given day without requiring much additional time. For instance, an individual might walk up a flight of steps each day instead of taking the elevator. These types of activities require less commitment than more formal fitness activities and are therefore typically more convenient.
