As of May 2021, at least 11 mountaineers have died on Mount Everest during the spring climbing season. This has been one of the deadliest seasons in recent years, with several deaths attributed to overcrowding, exhaustion, and altitude sickness. The high number of fatalities has raised concerns about the safety and management of climbing on the world's highest peak. **

Mountaineers use an oxygen device at altitudes of around 4000m because the air at higher altitudes contains less oxygen, making it harder for the body to function properly. This can lead to symptoms of altitude sickness, such as dizziness, fatigue, and shortness of breath. Using an oxygen device helps to supplement the body's oxygen levels, reducing the risk of altitude sickness and allowing the mountaineer to continue climbing safely. **

No, it is not true that many mountaineers claim to have reached the summit even though they have not. While there have been cases of false claims of summiting mountains, it is not a common occurrence among experienced mountaineers. Reinhold Messner, a renowned mountaineer, is known for his honesty and integrity in his climbing achievements. He is the first person to climb all 14 peaks over 8,000 meters without supplemental oxygen and is widely respected in the mountaineering community for his accomplishments. **

Data security and backup for WhatsApp refers to the measures in place to protect user data and ensure that it can be recovered in case of loss or damage. This includes end-to-end encryption for messages, which ensures that only the sender and recipient can read the messages, as well as secure storage of media and other files shared on the platform. Additionally, WhatsApp provides the option for users to back up their chat history and media to a cloud service, such as Google Drive or iCloud, to prevent data loss in the event of a device failure or loss. **

To change the Family Sharing storage on Apple, you can upgrade your iCloud storage plan by going to Settings on your device, tapping on your name, selecting Family Sharing, and then tapping on iCloud Storage. From there, you can choose a different storage plan that suits your needs. Keep in mind that the storage plan you choose will be shared among all family members in the Family Sharing group. **

Mountaineers or climbers retrieve the climbing rope and pitons/eye anchors when rappelling by using a technique called "retrievable rappel." This involves threading the rope through the anchors and then pulling one end of the rope while rappelling down, which allows the rope to be retrieved once the descent is complete. At the bottom of the valley, climbers can retrieve the ropes by either walking to the base of the climb and pulling the ropes down, or by using a technique called "releasable anchor," where the rope is threaded through the anchor in a way that allows it to be easily pulled down from the top once the climbers have descended. **

If the storage space for the WhatsApp backup is not sufficient, it may be due to the large size of the backup files. You can try deleting older backups or unnecessary media files from your device to free up space. Additionally, you can consider using cloud storage services like Google Drive or iCloud to store your WhatsApp backups, which offer more storage space compared to your device's internal storage. **
