Concordant with the functional roles of the brain structures that exhibit increased gray matter volumes, regular exercise over a period of several months has been shown to persistently improve numerous executive functions and several forms of memory.       In particular, consistent aerobic exercise has been shown to improve attentional control , [note 3] information processing speed , cognitive flexibility (., task switching ), inhibitory control , [note 4] working memory updating and capacity, [note 5] declarative memory , [note 6] and spatial memory .        In healthy young and middle-aged adults, the effect sizes of improvements in cognitive function are largest for indices of executive functions and small to moderate for aspects of memory and information processing speed.   It may be that in older adults, individuals benefit cognitively by taking part in both aerobic and resistance type exercise of at least moderate intensity.  Individuals who have a sedentary lifestyle tend to have impaired executive functions relative to other more physically active non-exercisers.   A reciprocal relationship between exercise and executive functions has also been noted: improvements in executive control processes, such as attentional control and inhibitory control, increase an individual's tendency to exercise. 
Limited evidence suggests that a person’s risk of heart attack during the first hour after smoking marijuana is nearly five times his or her usual risk. 73 This observation could be partly explained by marijuana raising blood pressure (in some cases) and heart rate and reducing the blood’s capacity to carry oxygen. 74 Marijuana may also cause orthostatic hypotension (head rush or dizziness on standing up), possibly raising danger from fainting and falls. Tolerance to some cardiovascular effects often develops with repeated exposure. 75 These health effects need to be examined more closely, particularly given the increasing use of "medical marijuana" by people with health issues and older adults who may have increased baseline vulnerability due to age-related cardiovascular risk factors (see " Is marijuana safe and effective as medicine? ").
Don’t give up on each other. It may take time and effort, but keep in mind that sexual touching between a woman and her partner is always possible.
