Final answer:
Shyla and Brendan should both maintain an active lifestyle to enhance their quality of life into their senior years. Shyla can exercise more to manage weight and blood pressure, and Brendan can support these healthy choices. Addressing such health aspects now will likely lead to a longer duration of healthy, active living.
Step-by-step explanation:
To maintain a quality of life into their senior years, it is important for Shyla and Brendan to take proactive steps. For Shyla, who is fit, active, but a little overweight and has high blood pressure, it is crucial to address these health concerns directly. Exercising more, particularly in a way that is enjoyable and sustainable, can help Shyla lose weight and manage her blood pressure. Cycling can be a good option, and while there are concerns about bicycle costs, road safety, and storage, these can be mitigated by looking for affordable second-hand bikes, finding safer cycling routes, or using stationary bicycles if outdoor cycling seems hazardous. Brendan's role could include being supportive and facilitating a healthy environment for both. This may involve being understanding but should primarily focus on shared healthy lifestyle choices, like staying active and eating well.
Moreover, exercising isn't just about physical health; it also benefits mental health, keeping the mind sharp and potentially preventing cognitive decline. Following a healthy lifestyle from now will greatly increase their chances of remaining active and healthy well into old age, much like many others who remain vibrant into their 80s or 90s. Therefore, the best option for Shyla and Brendan is to both maintain an active lifestyle and manage Shyla's health concerns.
