How would I prepare for a kundalini awakening when I'm not really spiritual and don't really want one?

So I'm 27 years old getting near the area where your body slowly but surely starts getting weaker as you age so I want to take care of it. I want to do semen retention, I already eat healthy, I want to start 20 minute meditation sessions, and maybe do short yoga sessions sometime in the future. I already know we can manifest in this world almost a expert on manifesting. I'm doing all of these habits not so much to have a spiritual awakening but because as my body gets older I want to remain healthy or age well yet doing a lot of these habits especially done together they say can also lead to a awakening.

So I have some questions 1) how to do all of these habits and not have a kundalini awakening or is that even possible? And 2) It still will be a while before I start meditating and do yoga. So should I just not add those two habits at all if I don't want one yet and am afraid?
