As you get older staying fit is even more important. Both for your ability to just function, and also I strongly believe it signals you've still got your sh1t together.
In my mid 40s I let myself go and got over 100kg (I'm ~6.3), but have dropped 10kg in the last 1.5 years and also gotten stronger. 2-3 sessions a week of Stronglifts 5x5 and riding instead of driving to work.
I reckon my head just works better as well. I find it much easier to concentrate for longer periods of time.
