Nowadays there are more divers at a higher age. They are eager to savour their active time as a diver as intensively as possible. Their well-chosen dive locations often lead them to the tropics and subtropics for long periods of time. There are also more divers at a higher age, not only on diving safaris. We know that older divers rather look for enjoyment than adventure. They also dive more safely, because they are more cautious and usually very experienced. They are also more willing to act responsibly and accept restrictions regarding their diving activities in case of physical limitations.
